LP1980302 Bootstrap: applied search filters display oddly

Moves the display of applied filters into bootstrap alert messages and aligns applied filters
in a row, and utilizes more native bootstrap classes.  Also, adds a label to the 'Locations'
filter and code to implement an 'OR' separator, if more than one location is selected.

To test:
1. Perform an advanced search in the bootstrap catalog and apply some filters. To test
the locations, select several location options.
2. Notice the formatting of the 'Filtered by:' display data.  Notice also the display
of the locations filter without a label or a separator.
3. Apply the patch.
4. Repeat 2 to see the new formatting.
