#54 No PASTE in mouse menu for text boxes

[Sean Keogh]

If a link in a node is set to be a text box, it is only
possible to paste text into that text box using CTRL-V.
Although there *IS* a right-click mouse menu, it only
appears to have the COPY function, no sign of PASTE.

A lot of less computer literate users don't know about
keyboard shortcuts, so having PASTE on the right-click
menu in text boxes would be very useful.
