Localization and font changes

* Changed StyleEditor to FormatDialog in L10NSharp keys
* Added OpenSans to default font lists for Linux use
Adjusted tab words, upgraded gradients on controls
Give font size and line height combos more space

* also moved <select> element margin-left from html to css
Tab width should now handle longer localized tab names

*Also Reduce :hover precedence so selected tab doesn't hover
BL-662 localize tabs

* this wasn't working before, but seems to now!
Fix tab-changing bug and remove colon
Found more places to replace StyleEditor w/FormatDialog
Merge branch 'master' into MoreFormatDialogWork
BL-718 make default button be "no" instead of "yes"

When adding copyright info to an existing picture, don't
default to "copy this information to all pics in this book"
Removing tabSelected(n) completely seems to work fine
