Manipulation: Switch rnoInnerhtml to a version more performant in IE

Browse Source 
IE versions greater than 9 do not handle the old regular expression well
with large html content. This is due to the use of a non-capturing group
after a very common html character (<).

Test suite: http://jsfiddle.net/Lwa0t5rp/3/
Microsoft bug: https://connect.microsoft.com/IE/feedback/details/1736512/

Fixes gh-2563
Closes gh-2574
