Replaced back protected private UID with unprotected one.

This should simplify development for contributors as they won't have to
generate and replace the UID all the time. The protected one was left
commented in the code.
Replaced my nickname with the full name in AboutPage.
Few updates to .gitignore:

- excluded files created by Symbian in-source builds;
- excluded files created by Harmattan in-source builds;
- excluded moc, obj and rcc dirs which are forced by Qt Creator when
  building for Harmattan target.
Fixed few rules in the project file:

- instead of excluding all other possible platforms for Maemo/Harmattan
  booster, just test for Maemo/Harmattan;
- don't include/build mainwindow.* files when targeting Maemo/Harmattan.
