Update Table Component

- Added new mixin for flexbox tables (`flex_table( {integer} $colCount )`)
- Implemented 12-column `.flex_table` class
- Base styles are for mobile, with an override for a larger viewport
- Extremely thin implementation to allow for the component's use in various contexts
- Child class names consistent with those of `.table` for easy adoption
- Bumped bower version to 1.3.1
