This way the forum and private group client do not need to keep track of
message timestamps themselves and do not need to interact with
post/message factories.
Null safety annotations
The @NotNullByDefault annotation marks all fields, methods and parameters in a class or package @NotNull, so Android Studio will warn if values that may be null are used. Please use this annotation for new classes, and specify @Nullable for any fields, methods and parameters that may be null.
Injected fields are initialised to null, so injected classes should use @MethodsNotNullByDefault and @ParametersNotNullByDefault, or specify @Nullable for injected fields.

Forum controller thread safety and tree safety
This branch solves the concurrent forum issues by code restructure and refactoring.

Like other recursive operations on the dependency graph, this is
not done in a single transaction to prevent an attacker from creating
arbitrary large transactions.
So at startup, the `ValidationManager` finds and resumes any
unfinished operations, by looking for shared messages with unshared
dependencies.
Add one introduction test for modified response message
This is only the first part of #627, but I am putting it up for review already, since the second part will be very similar and issues found here will likely apply to both.

Add support for comments and reblogging to Blog Client
Comments and reblogs need to depend on the post they refer to.
Since message dependencies are limited to one group,
the post and also the comments need to be wrapped
when commented on or reblogged to another blog (and group).
For this reason, in addition to comments, two new wrapping message types
are introduced. They retain all data of the original messages and allow
for reconstruction and signature verification.
This MR breaks backwards compatibility with old blog posts.
It removes the content type, title and parent ID from the post.
Furthermore, it includes one commit that replaces the `Message` in `MessageSharedEvent` with a `MessageId`.
Closes#494

Before the introducee sends her ACK,
she derives a master key from the ephemeral shared secret as before.
Two nonces and a MAC key are then derived from the master key.
The local introducee signs one of the nonces and calculates a MAC
over her own identity public key, ephemeral public key,
transport properties and timestamp.
The local introducee includes the signature and MAC in her ACK.
On receiving the remote introducee's ACK,
the local introducee verifies the signature and MAC.
Should the verification fail, an ABORT is sent to the introducer and
the remote introducee that was added as inactive is deleted again.

Blog controller thread safety
This patch removes the mutable list of posts from the blog controller to make it thread-safe, and adds a cache of message bodies to speed up reloads.
Closes#555.

Allow unsubscribing from shared blogs
Only personal blogs from non-contacts can be removed.
This also adds integration tests that check the conditions under which blogs can actually be removed.
Closes#579
