Added syntax highlighting to README (thanks @neXter)
Convert typedef'd ENUMs to use NS_ENUM() macro

This has plenty of benefits, including better code completion and error
checking than other methods.
Merge https://github.com/SlaunchaMan/FCModel
Rewrote instance uniqueness to be much simpler since FCModelCache no longer performed actual caching (that was old, unreleased behavior).
Added podspec, I think. It's my first time, be gentle

Remove deleted entities from global instance cache
Fix deadlock in -instanceWithPrimaryKey
Some codepaths through instanceWithPrimaryKey can result in a database request, which will
be serialized through g_databaseQueue. If a separate thread has already acquired the g_databaseQueue
lock and is waiting for g_instancesReadLock, then a mutual deadlock will occur. This fix releases
the g_instancesReadLock before any database calls are made.

Fix deadlock in -instanceWithPrimaryKey
Add method to close current database

This is useful the following cases:

- An app might only use FCModel infrequently and wants to free up resources.
- An app might want to allow the user specify (or change) where its data is stored.
- Unit tests work best if each run starts with a 'clean slate'.

This changeset also includes some initial unit tests for the library (which relies on the ability to create a fresh database for each test).
Added *.xccheckout to gitignore
Make closeDatabase a private category for unit tests
Merge pull request #7 from dhennessy/add-db-close

Add method to close current database for unit testing only; add some unit tests
