Add mappable commands for system clipboard

Browse Source 
System clipboard integration exists now in two favors: typable and
mappable.

Default mappings are:
- SPC p: paste clipboard after
- SPC P: paste clipboard before
- SPC y: join and yank selection to clipboard
- SPC Y: yank main selection to clipboard
- SPC R: replace selections by clipboard contents
