Refactor key mapping modifier logic

Browse Source 
- Consolidate a modifier's "left" and "right" variants to just one
  modifier referred to by its name or mask. E.g. Control_L and Control_R are
  resolved by detecting the mask and are both associated with the name "Ctrl".

- Store string representations of the modified key values as the keys to
  the key entry map (exactly how they appear in the config file). E.g.
  the string "Ctrl-m" would be the key to the map entry for a custom
  Ctrl-m binding (whereas before the key would've only been "m", a
  source of ambiguity and conflict).

- During init, pass through key mapping entry logic twice: once for
  inputting the defaults, and a second time for adding any custom
  mappings as defined by the config file. This allows defaults to stay
  in place unless a user chooses to blow them away. E.g. mapping Ctrl-p
  to key_up shouldn't blow away key_up's default mapping to up arrow,
  and this fixes that use case.

These changes resolve several bugs due to key mapping resolution ambiguity and
conflicts, and generally make key mapping more intuitive. However, a new quirk
is that keys that are obtained using Shift (like "J", aka "capital j") now
require the use of Shift modifier when configuring that binding.

wofi \- Key names for custom binds
.SH DESCRIPTION
This is a list of the key names that can be used for custom binding, these are taken from gdk/gdkkeysyms.h. Certain keys cannot have the shift modifier attached as holding shift while using these keys causes a completely different key press to be registered. For example Shift_L\-j is invalid as holding shift while pressing j changes the key into J so J should be registered as the key instead of Shift_L\-j. This is the case with all alphanumeric chars as well as Tab which turns into ISO_Left_Tab.
