Sækja keymapper 5.0.0

The reason for the major version number increment is mainly because of the changed behavior of ;. Up until 4.9 it was documented to start comments like #. Otherwise all configurations should work like before.
Added
- Allow to separate multiple mappings on one line with ;. This is useful for macros which generate multiple mappings. e.g.:
swap = $0 >> $1 ; $1 >> $0
swap[Y, Z]
- Allow to add mappings for inputs which are released. e.g.:
# trigger when A is released
!A >> B
# trigger when B is released while A is held
A{!B} >> C
# trigger when B is released while A is NOT held
!A !B >> C
- Toggling virtual keys can also have immediate effects. Using them as modifiers is toggling them twice:
# toggle Virtual1 before and after pressing B
# this effectively maps D to A B C
Virtual1 >> A ^ C
D >> Virtual1{B}
# {} may also be empty. This maps C to A B
Virtual2 >> B
Virtual1 >> A Virtual2{}
C >> Virtual1{}
- Automatically replace Virtual with an unused virtual key. e.g.:
# assign different virtual keys to VimMode and CapsWord
VimMode = Virtual
CapsWord = Virtual
- Added keymapperctl operation --notify for showing notifications (#282). e.g.:
notify = $(keymapperctl --notify "$0")
F1 >> notify["Test"]
- Added toggle-active directive, which allows to set a sequence that de-/activates keymapper (#283). e.g.:
@toggle-active ScrollLock
- Added include-optional directive, which includes a file but does not fail when file does not exist.

Fixed
- Fixed suppressed modifiers getting reapplied (#291).
- Fixed loading config from "%HOME%\.config\keymapper" on Windows (#292).
- Properly releasing keys when UAC prompt appeared on Windows.
