[ptx] moved hugin FAQ to panotools wiki

[Pablo d'Angelo]

Hi all,

I have moved the hugin FAQ (frequently asked questions) to the panotools
wiki. I hope that this will make it easier to actually provide a useful FAQ
(the current FAQ hasn't been updated since years...)

It can be found at: http://wiki.panotools.org/Hugin_FAQ

Since anybody can edit the wiki, instead of just me and Bruno, please add an
entry if you think there should be one.

ciao
  Pablo
