* move one usage of Firwmare method into Firmware config where it is better suited
* PathManager - remove unused code
* move some PathEntry specific logic out of PathManger and into PathEntryCollection extension methods
* PathManager - detangle some exe pathing logic from Global.Config usage, clarify what a completely broken method should actuall do
* move more logic from PathManager to PathEntryCollection extension method
* move absolute path creation to PathEntryCollection, lots of refactoring and simplifying of PathEntries usage
* simplify PathEntryColleciton usage more
* simplify PathEntryCollection more
* break PathEntry classes into separate files, a bit of cleanup
* move Rom path logic out of PathManager into PathEntryCollectionExtensions
* move config UseRecentForRoms and LastRomPath into PathEntries, note that this is a breaking change for previous configs, those values will revert back to default values
* move SaveRamPath logic from PathManager to PathEntryCollections
* move cheats path logic from PathManager to PathEntryCollection
* move another method out of PathManager
* move some Retro hacks to PathEntryCollections, exposes more implicit dependencies
* move savestate logic out of PathManager to PathEntryCollection
* move more logic out of PathManager
* move some savestate logic out of PathManager, move most to MainForm where it is used, detangle some implicit dependencies from SaveSlotManager
* rename method
* move more logic from PathManager to PathCollectionEntry
* movie final Global.Config.PathEntries logic out of PathManager and into PathEnties
effectively resolves#1200
* Replaced floats in FloatRange with ints (would have used shorts but
SubGBHawk/SubNesHawk use an axis to hack in cycle count or something), added
both Range<int> and Range<float> auto-properties
* Added bool field IsReversed to FloatRange
* Added enum AxisPairOrientation and factory method using it
* Cleaned up usages of FloatRange fields and properties
* Added new properties to PadSchema.ButtonSchema for type
PadInputType.AnalogStick (to hold the two FloatRanges) and used
ControllerDefinitions from cores to dedup these ranges in the schemata
* Made VirtualPadAnalogStick work properly: both the direction and bounds are
correctly set from the controller schemata, the polar conversion measures angles
consistently (though I think it might not work outside -128..127 e.g. for PSX),
and I didn't break the sensitivity override, plus negative percentages might
work now but I didn't allow those
* Renamed FloatRange to AxisRange, but did not rename related symbols
