home: make sure users and group autocomplete is case insensitive

Both SQLite and MySQL have a case-insensitive LIKE operator by default, but
PostgreSQL does not. As a result, a query for 'john' does not match the user
'John Doe'.

As case-insensitivity is most user-friendly in the context of autocompletion
of users and groups, switch to the ilike() method of SQLAlchemy rather than
like().

==================
Repository locking
==================

Kallithea has a *repository locking* feature, disabled by default. When
enabled, every initial clone and every pull gives users (with write permission)
the exclusive right to do a push.

When repository locking is enabled, repositories get a ``locked`` flag.
The hg/git commands ``hg/git clone``, ``hg/git pull``,
and ``hg/git push`` influence this state:

- A ``clone`` or ``pull`` action locks the target repository
  if the user has write/admin permissions on this repository.

- Kallithea will remember the user who locked the repository so only this
  specific user can unlock the repo by performing a ``push``
  command.

- Every other command on a locked repository from this user and every command
  from any other user will result in an HTTP return code 423 (Locked).
  Additionally, the HTTP error will mention the user that locked the repository
  (e.g., “repository <repo> locked by user <user>”).

Each repository can be manually unlocked by an administrator from the
repository settings menu.
