Bug with boostrap 3 in fade mode

[chrvadala]

Hi,
I have found an incompatibility issue with bootstrap3.
In fade mode panels are not shown.
The cause is this bootstrap css class that add an opacity: 0;

I have solved this bug simply by removing component-animations from my project, but I think that this should be solved in this project.

Thanks, I'll have this fixed in the next update.
