Add info section to task page and display executor guid there (Resolves #29)
Remove unused data attribute
Change default sort order for active/paused requests page to reverse `timestamp`
Fix search input styles on small device sizes
Add delete and unpause actions for paused requests (Resolves #27 and #28)

@wsorenson did not test this b/c there are no paused requests atm. If you create a few I'll double check this actually works. =)
