This commit introduces an abstract `BaseContactListAdapter` which provides most of the adapter logic. The original `ContactListAdapter` extends it to show date and online status of the contacts. The new `ContactChooserAdapter` which is used for introductions extends the `ContactListAdapter` and adds logic for graying out contacts from different identities than the currently used one. A new `ContactSelectorAdapter` extends the `BaseContactListAdapter` and allows to select multiple contacts. It offers a method to return a collection of all selected `ContactId`s. This commit also sneaks in an animation when the 'Share Forum' button is clicked. Closes #292
