Now more closely resembles the published template.

* Corrected DiVA link format, trimmed trailing whitespaces, added todo list from todonotes package (if loaded)

* commented out Georgia font selection in settings.tex and
* corrected class option to 'lith' instead of 'tekfak' in main thesis file

* Cleanup of outcommented sections of liuthesis, * added template text in student thesis demo, added Arial as fallback font option for XeTeX

If the option printerfriendly isn't used, there used to be no page
break before the start of the first chapter. This meant that arabic
page numbering (i.e. page 1) started already on the last table of
contents or "list of" page (that should have a roman number like vii).
