Less'd version of jquery-ui bootstrap theme.
The index.html and components.html use the less.js and less styles instead of bootstrap css as well as jquery css.

Most of the code is inspired by @basejump's version which is not updated in a while.

Only buttons are correctly getting rendered as of now. Other changes are coming ..
Minor tweaks to the buttons to cover non-standard button cases.
Update jqGrid.overrides.css

Solves the highlight issue on IE10.
