vis: put in visual mode should replace the current selection

There are some combinations (e.g. line wise selection / character
wise register content) which should probably be improved further.

Also since vis currently neither supports the numbered registers
"0 - "9 nor the small delete register "- the deleted text is
not stored in any register. Notice that we can't call op_delete
in the implementation because it would overwrite the register
content we want to paste.

Closes #113
