Filter Mapping Breaks when hiding columns.

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Build table with Server side processing and select more columns than you're 
going to show.
2. Hide columns using mDataProp and "bVisible": false.
3. Setup filters for each column, setting those you don't want visible to "null"

What is the expected output? What do you see instead?
Everything appears to render correctly, but the filters are now mapped to the 
incorrect columns.

What version of the product are you using? On what operating system?
Most recent.

Please provide any additional information below.

I would also note, that when typing into the notes column, if appears that the 
search box has become a global search box as well... this is becoming quite 
frustrating. I'm using this with a drill down view, so I need to pull more data 
than I initially want to show.
