Auto-upload favorite local page

[TinyRaindrop]

Resolves #38

1. [x] Has settings switch.
2. [x] When enabled, adds fav buttons and you can set one local page as favorite.
3. [x] In champ select, after locking in, this page will be uploaded if current champs matches the one you picked.
4. [x] new strings added to all locales.

Obviously, needs some testing (practice tool lobby works great).

Anyone can test this pull request:

git remote add upstream https://github.com/Soundofdarkness/RuneBook.git
git fetch upstream pull/41/head:favpage
git checkout favpage

This creates local branch 'favpage'

Looks pretty good so far, I'm just going to wait with merging this one until the theme stuff is stable, so we can test it on a clean version.
