Several fixes to the training system

Today, we've continued to work with the new training system, and we are now getting a really good grip on things.

The following fixes have been implemented today:

• Crash during training if you had a training group with the "Crossing" exercise
• The wish list now shows the new training averages.
• Player comparison now uses the new player abilities.
• Fixed a javascript-crash, which meant that IE10 users in some cases could not load the training group pages.
• IE users will now see intensity selector as an old-fashioned dropdown menu because IE doesn't work properly with the HTML5 slider.
• Fixed layout bug on Windows on the training statistics pages.
• You can you use the "Last X days" and "Date interval" search options on the training statistics pages..
