Removed use putty as ssh client*

Added PuTTY session import
imports ssh only currently, supports username, hostname, port, and port forwards**
Fixed small sizing bug on initial tab creation. It would set height to the form's height instead of panel

* This is SuperCygwin, if you REALLY want putty its simple to make custom presets.
** Only known to work with standard Local and Remote forwards
