Title: fixed some bugs with wrapped foldlines

Hi

folding of wrapped lines was broken, fixed that and some small issues along the way

- findPrevious finds same text again and again if selection isn't backwards
- selectAll+removeLines corrupts undo history (simple typo first<=> last)
- it was impossible to use number keys from Numpad in commands

also on new versions of firefox userAgent changed to

"Mozilla/5.0 (Windows NT 6.1; WOW64; rv:11.0a1) Gecko/20111113 Firefox/11.0a1"

which was setting `isOldGecko` to `true`
