Issue with dynatable on Firefox

[lucernae]

On Firefox, sometimes dynatable's code failed to run if the table content is really big.
This is coming from the intended limitations by Firefox to limit pushState cache.
It will raise NS_ERROR_ILLEGAL_VALUE exception in Firefox, and since it comes from the OS, it can't be catch.

Hopefully fixing this issue will fix several issues with Firefox (like #199 #172 )
