Fix performance of splitCssText (#1615)

Browse Source 
- Fix bug where the right split point was not being picked for the 3rd section onwards
- Fix that it wasn't able to find a split when both halves were identical
- Add test to put splitCssText through it's paces with a large file
- Introduce a limit on the iteration which causes the 'efficiently' test to fail
- Fix poor 'crawling' performance in the 'matching' algorithm for large css texts - e.g. for a (doubled) benchmark.css, we were running `normalizeCssText` 9480 times before `k` got to the right place
- Further algorithm efficiency: need to take larger jumps; use the scaling factor to make better guess at how big a jump to make
