More Directory Formatting (#108)

This makes the following changes
- allow directory rows to overflow their container on resize (allowing
scroll as a temporary test)
- fix directory width to account for resizer width
- add ellipsis to name column on table resize
- add the rightmost resizer back (more as a temporary test)
- do not search when the filtered contents are empty
- cap the index to the end of the list of the number of entries becomes
less than the current index
- do not redo backend call on filter or search of directory results
- add letter spacing on header row
