XF2 Style Omni 2.1.10

Changes

• Removed template "xb_canvas" as it was no longer used (all Canvas HTML edits are inside PAGE_CONTAINER now)

Fixes

• Boxed navigation wasn't stretching with alternate page width
• The search bar in sub-navigation now has some spacing on the right side
• Space added before our copyright so it's not touching the default XF copyright.
• Sticky sidebar had no spacing when sub-nav was floating as well
• Removed an unnecessary line at the end of "jquery.qtip.min.js" causing a server error in some cases
• Mod selected color wasn't working if the alternate background on discussion items was enabled
