Refactoring

In EasyIni
* Better handling of empty sections.  The previous reversion broke that
functionality.
In AHK Split.ahk
* SpecialHKsDlgEnableDisable for Special Hotkeys dialog. Fully
functional, now.
* LoadSpecialHKs got an overhaul for ini integration.
* SpecialHKsDlgModifyHK() to handle hotkey edits in Special Hotkeys
dialog.
* Renames
* Exclusion of unsupported or unneeded hotkeys in
ConvertWinSplitHotkeysXMLToIni().
* LV_GetSelText to work for any column.
