PR2 v157.2: Happy Holidays!

[bls1999]

Happy Holidays! This update contains two new sets, some small changes, and a few bug fixes.

Changes/Additions

• Added two new sets. The Christmas and snowman sets are now available on the first six levels of the holiday campaign.
  
• You can now zoom to 75% and 500% in the Level Editor. Hooray for visibility!
  
• Epic Upgrade prize popups will now show a small message when you win. In an effort to quell the continuous questions about why someone's shiny new part isn't appearing for them, there is now a message letting you know what exactly you just won.

Fixes

• Level lists now update at an appropriate interval. Thanks to @Vaza for reporting this.
  
• The loadouts button doesn't disappear when hovering or clicking anymore. Thanks for reporting this, @Lego-man945.
  
• Ranking up to 3 or 20 no longer requires you to log out before being able to send PMs or create a guild. Thanks to Camer for reporting this bug!

Public Beta

This update contains some code to a couple of beta features:

• Tablet gestures in the LE (placing lines of blocks, dragging, artwork, etc).
  
• Pressing and holding the CTRL key (also includes ⌘ for Mac) to switch from a selected LE tool to the delete tool and releasing it to return to the previously selected tool.
  

The reason these are being released in beta is that they require testing across platforms. Please help with the testing of these features and post in Bugs & Suggestions if you find anything. Thanks!
