Updated datagrid filtere to auto focus

Updated datagrid filtere to auto focus
on the first input on the filter, also added
key event for the enter key to apply filter.

Testing:
Test this by testing that all filters on the all
datagrids now auto focus on the first input on
the datagrid and that when enter is pressed the 
filter gets applied to the datagrid.

NOTE: filters with drop down will require that you
enter twice since the first enter will take you into
the dropdown options.
