Selection should not be visible during mouse interaction mode

[dbkaplun]

Steps to reproduce:

npm install -g slap
slap /path/to/somefile
# use the mouse to select some text
# notice that a blue selection marker appears via xterm.js
# but other terminals use slap's built-in selection mechanism

Thanks for reporting @dbkaplun. This should be partially fixed by now after #148.

The current issue is that you get both slap's selection and the native one. I guess we should disable text selection, when term.applicationCursor is true.

Fixed in #670
