Improve text selection behavior

[Tibolu]

It would be really convenient if we could select a line of text by triple clicking on it.
Right now, it just deselects the word that gets selected by the two previous ones.

This would give us a nice coherent behavior : 2 clics: select a word, 3 clics: select a line, 4 clics: deselect

Hold down the CTRL key and double click, it should select a line.  to deselect just click once, no key modifier needed.

I should have tried that.
Thanks a lot!
