Private Group List UI
This MR implements the UI for the list of private groups.
It reacts to three types of events to refresh the displayed data:
* new group message received
* private group added
* private group removed
Missing from final implementation:
* entering groups
* adding new groups
* reacting to a future group dissolved event
* actually removing a dissolved group

Fix NPE when stopping KeyAgreementTask, improve thread safety
This branch fixes#696 and improves the thread safety of the camera code, mostly by adding @UiThread annotations and occasionally by moving stuff onto the UI thread that might have happened on other threads before.
Closes#696

Clean up identicon code, remove unused classes
I noticed some debug-level logging coming from the identicon code, went in there to remove it, and realised half the code was unused, so I removed that too.
No functional changes except that the logging is gone and the opacity is now OPAQUE rather than UNKNOWN, which wasn't valid in this context.

Emoji Support for all user input
All text that can be generated by users will show emoji from the shipped sprites by using the `EmojiTextView` instead of the normal `TextView`.
For all messages and posts, the custom emoji keyboard is now available as well. For this, a new `LargeTextInputView` has been introduced that is a sub-class of `TextInputView`. In order for the emoticon keyboard to work properly the existing views had to be modified heavily, sometimes resulting in new behavior such as scroll views now being above the fixed input field. Actual testing on a device (preferably with a tiny screen) is recommended to make sure this still works as expected. Screenshots will be included at the end of this post.
This MR also disables menu actions rather than hiding them and it includes a fix for a regression that was not showing the keyboard automatically in forums.

Try harder to find suitable camera parameters
This branch fixes QR code scanning on the Galaxy Nexus running Cyanogen Mod 12.1 (Android 5.1.1), without breaking QR code scanning on any of the other test devices.
The problem on the Galaxy Nexus was that the selected scene mode was overriding the selected focus mode, so we asked for continuous picture mode but got macro mode. Macro mode requires startAutoFocus() to be called, but we weren't calling it because we'd asked for continuous picture mode.
The fix for that problem is to query the focus mode after applying the parameters and call startAutoFocus() based on the actual mode rather than the requested mode.
But then I discovered another problem: barcode scene mode was setting the flash to auto, so in low light the flash was turning on and off while trying to scan QR codes. That might work well for printed QR codes, but it's terrible when scanning from a screen.
The fix for the new problem is to select barcode scene mode, then try to disable the flash, and if that fails, reset the scene mode. Then we pick the best available video stabilisation, focus mode and preview size.
On the Galaxy Nexus with CM 12.1, that means we use continuous picture mode instead of barcode scene mode, which works fine. All the other test devices pick the same settings as before.

Check whether File#listFiles() returns null
The docs say this can happen if there's an I/O error. Also fixed a throw-in-finally-block warning and renamed an IoUtils method to make its contract clearer.

Remove base32 TODOs, fix a potential NPE
I thought we'd be able to get higher data density in QR codes by using base32 instead of base64, allowing the QR code to use alphanumeric mode instead of byte mode. But I tried it, and although the QR code does use alphanumeric mode, it comes out at exactly the same size (see the 346-use-base32-for-qr-codes branch). So this MR removes the TODOs and fixes a potential NPE I spotted while working on the other branch.

Recreate cache directory after deleting app data
This fixes a warning on the Moto G:
```
E/libEGL: error creating cache file /data/data/org.briarproject/cache/com.android.opengl.shaders_cache: No such file or directory (2)
```
@grote might possibly be related to hardware rendering issues.

When the user enters a private conversation after adding her second
contact, an onboarding screen will be shown highlighting the possibility
of introducing the contacts to each other.
