Removed now duplicated PathEquality class from Desktop Ponies assembly as it is now in the Desktop Sprites assembly.
Created a form accessible from the second editor for finding images not adhering to the 2x scale style.
Fix WinFormSpriteInterface.LoadImages to not hang if the collection was empty.
Fix games to constantly refresh destination when returning ponies to their start position. This is because if a player switches the pony they control during this phase, the destination overrides will be cleared and thus need to be refreshed or the pony no longer being controlled will just sit idle.
Added some checks in Options to ensure some values loaded from file were in a valid range.

Removed warning about scale factors other than one when starting games as it no longer applies.
Enforced maximum scale of 4 in the OptionsForm (was previously 5 on the form but 4 in the context, leading to an exception).
Added missing check for speech chance being a normalized value in PonyContext.
