GTK*: Action Replay cheat menu (+ other cheat improvements) (#847)

* GTK cheats UI inputs/displays hex for address (offset)

* Added range bound to keep internal cheat data within specified size
The decision to change the value column to store G_TYPE_UINT is purely pragmatic--having all data be treated and displayed as unsized is simpler than writing a custom display to handle signedness and cleaner than 1-3 byte ints appearing unsigned and 4 byte int appearing signed.

* Added index and cheat type data to ListStore
My implementation plan is to use a GtkTreeModelFilter to create separate section for internal and ActionReplay cheats, but I was not convinced the indices in the tree path would correspond to the indices in , hence the additional column.

* Filter raw and AR cheats, display both filters in UI, patch up raw update/delete

* Action Replay UI elements [GTK]

* Memory leak fixes
+ some additional clean-up comments and small bug patches

* Backport to GTK2
