Use new MagicalRecordStack defaultStack in tests
Remove all tests and test targets
Add checks for NSBooleanAttributeType and NSStringAttributeType in the NSAttributeDescription data import category
Always import if no `-(BOOL)shouldImport<#Attribute#>:(id)data` method is implemented
Make creation/deletion methods on NSManagedObject more consistent
Rename `+ MR_defaultURLForStoreName:` and `+ MR_urlForStoreName:` to
`+ MR_fileURLForStoreName:` and `+ MR_fileURLForStoreNameIfExistsOnDisk:`

This should make their purpose clearer, although I still have some concerns
about `+ MR_fileURLForStoreNameIfExistsOnDisk:` being public, namely that it's
not something the library should need to provide to users of this category.
Adds `options` dictionary to all of the NSPersistentStore creation methods

This is in support of not having to specify a default stack, and also creating
temporary entities without a managed object context.
Adds `MR_isEntityDeleted` to the NSManagedObject+MagicalRecord category

NSManagedObject's `isDeleted` method does not work reliably. Checking if the
object's NSManagedObjectContext is nil in addition to the standard `isDeleted`
method is one way of determining if the object has been (or will be) deleted.
Conversion of dates on import should assume GMT, not the user's current locale
Remove commented out code
Formatting and method ordering
Add method to delete a persistent store at a provided URL, along with all sidecar files (`-shm` and `-wal`)
Tests!
Reorganise project files so that no build related artefacts are stored in Library

This means that the Library folder can be dropped into any project without customisation.
Setup Travis CI
Remove MR_SHORTHAND support
Update Podspec to exclude UIKit categories from OS X, and add myself to the author array
Add MRDeprecated() for marking methods as deprecated
Provide deprecated versions of the shorthand methods

This will aid users making the transition to MR_ prefixed methods, as it will
mark all shorthand uses with a deprecation warning and provide the correct
method to use in the warning. It's pretty nifty.

Shorthand is enabled by default now, but any time it is used there's a warning.

Also, there's a kickass ruby script for regenerating the
MagicalRecordShorthand.[hm] sources automatically. Oh yeah! :boom: :fist bump:
Remove commented out ARC check — the project is set to compile with ARC
