Symbinode v0.1.1

This is the first set of fixes for Symbinode v0.1 
Fixed some minor bugs and improved textbox functionality. 

Fixes:

Fixed incorrect connecting line behavior when disconnecting and connecting to a node in some cases.

Fixed an error in text fields when copying and pasting values.

Fixed the scrolling behavior in the parameters tab.

Fixed colors of active pickers in the Color ramp node, now it is more obvious which one is active.

We will continue to work on the bugs and stability of the program.
