Migration version now falls back to -1 if no document exists.

A log file path can now be set via `arsnova.log.file` Java system

* arsnova.log.exceptions
* arsnova.log.level
* arsnova.log.level.root
* arsnova.log.level.spring
* arsnova.log.properties

Currently supports finding contents by `roomId`.

Consistently use singular for packages which contain mixed kinds of
classes. Moved a few classes to packages that better fit them.

We now use the format property instead as type ID for Jackson. A custom
TypeIdResolver is used for the mapping.

`skip` has a huge impact on performance and is not intended for
pagination. Bookmarks perform much better.

Additionally, increased socket timeout for migrations.

Additionally, added log warnings for skipped entities.

Before migrations are run we now make sure that the database is empty or
that a MigrationState document exists. If that is not the case,
maintanence mode is activated to prevent data loss.

Startup failed before if no second database for migration was available.

Fixes #19.

Add support for sub paths and remove restriction of HTTP methods.

This was causing issues with aliases containing dots.

Entities can now be retrieved interally without authorization checks. In
this case, the entity is marked for internal use and serialization is
prohibited.

Fixes regression introduced by commit
7eec95ae.
