allow copy paste in a text area directly in tool pages

[tougai]

Wouldn't it be great to have a thourth icon in the input menu (see bellow) of a tool to allow users to copy and paste some text instead of having to first import it in the history ?

I mean, the history import could still be done, but in the backend and automatically, like if we were using a workflow (which is the work arround we have found to do this).

This could could improve the user experience without having to click at least 4 times before to be able to run the tool.

Think of someone who wants to quickly blast a sequence against NT in order to check a read to see if it is a contamination of some sort.
