IE11 fix, for mouse hovers. Changed /MSIE/ to /((MSIE)|(Trident))/

I ran a build and the fix looks good. 

This is basically an alternate, current version of this thread:

Looks like a couple of lines related to border colors changed as well, guess the source must have been changed recently since I didn't touch that code in the source file. I tested the setting border options using the built files like that and they still work perfectly so no worries
