Add possibility of using space with braille dots

[nvdaes]

Link to issue number:

Fixes #4

Summary of the issue:

Though gestures can be assigned from NVDA's Input gestures dialog, maybe convenient to add commands available in braille keyboards, using the space bar in combination with braille dots to move the system cursor or similar tasks.

Description of how this pull request fixes the issue:

inputCore.manager.userGestureMap is updated with entries added to the global plugin module, to assign gestures to globalCommands.GlobalCommands.

Testing performed:

Tested the plugin and several commands, also using one hand mode.

Known issues with pull request:

If gestures are reset from NVDA's Input gestures dialog, these gestures will be removed from userGestureMap until the plugin is loaded again, for example with NVDA+control+f3.

Change log entry:

• You can press space bar in combination with braille dots to emulate gestures, similar to commands available in braille displays.
