ptpyvim / pyvim copy / paste usability issues

[clach04]

From #46

Under Windows with "version 3.0.3, prompt_toolkit 3.0.38", Paste from Windows/System Clipboard using either keyboard or mouse does not work. Using mouse to paste moves cursor.

Similar for Linux terminals, like lxterminal.

Fix implemented to disable mouse mode support in pyvim a885da9

Under Windows workaround, use the CMD top right menu to mark/copy and paste.

Disabling pyvim mouse support doesn't resolve but does help.

• Better workaround, issuing set nomouse allows right click menu to come allowing both mark/copy and paste from right click which is faster/more-convenient to CMD menu. Keyboard paste still does not work
