Since consistency in code is most important, 'ToxId' is used
for code, whereas 'Tox ID' anywhere outside of code.
Also fixed wrong comments in core.h:
* qTox gets only public key of a grouchat peer, not their
Tox ID
* qTox tries to return full address (Tox ID) or public key
The qTox Project is not associated with the Tox Project in any ways, with the exception of "qTox" using the Tox Projet's "toxcore" collection of libraries.
In particular, the Tox Projet does not own copyright over the qTox Project's "qTox" collection of software, source code, and assets.
The qTox Project's assets are under the sole copyright of the qTox contributors, and no partiular rights are granted to the Tox Project.
New friends must be added to the friend list before loading history, otherwise the history code won't find the friend in the friendlist, and the history will have blank names for the friend
friends list. Widgets are sorted upon being added to the friends list in
the first place, and re-sorted if a user changes their name, or if a
user is given an alias.
-Friend now inherits from QObject
-Friend objects now emit a signal when their display name is changed
-FriendListWidget::moveWidget() is now a slot
Instead of names. Fixes#603
Groupchats still use names internally, since there's currently no way to get a chat member's public key throught the toxcore API
