Grid theme and bootstrap templates

added a theme property to the grid
Added a bootstrap template for each grid
so when the theme property is set to bootstrap it uses this template

deleted some duplicate files Grid samples
for example myFiles, publicFiles , which were being duplicated by My Files and Public Files

Some new bootstrap samples

Some general grid fixes for sorting and broken links

Added oneui classes to the grid div, so that when a grid is used
in an application that may not have the correct classes applied to the body
the grid will still renderer correctly

Changed some strings in i18n.js to match the strings in connections
