update variables to inlude @baseFontSize, @baseFontFamily, @baseLineHeight for easier customization; added placeholder for @primaryButtonColor, but didn't implement

huge update to forms, docs for the new forms, added a new link for js example to tabs/pills, add some new mixins

remove theme.less and split preboot.less to mixins.less and variables.less to isolate customization from function

bump css to 1.3.0, update makefile to reflect that, update form css to prepend form to the .clearfix to prevent some bullshit, small tweaks elsewhere

updated container mixin to be fixed-container instead so we can keep the .container in scaffolding while removing the repeated code

improve CSS properties for centering content, the container, and fluid container so as to not override properties where possible

add reset filter to preboot for turning off gradients in IE when necessary; make :disabled [disabled] for crossbrowser usage

redefine the grid to use attribute selectors with css regex, make previously fixed grid values use variables we use elsewhere

merged in my pending changes from 1.2-wip branch, resolve diffs as best as i could, update docs and alerts to use original classes, updated docs to include smaller section for layouts

pull filter gradients out completely because IE can't render them correctly in half of all instances and they are performance problems with them; tweak alert message styles, particularly close button;
