Client side overhaul.

Most importantly, upgrade to Bootstrap 3 and use vanilla Bootstrap interface
for SequenceServer:
  a. modern
  b. easily themable later
  c. need bootstrap for upcoming changes
  d. thus cleaning up custom.css

Add SequenceServer sub-title in navbar.

Use monospace font for sequence textbox.

Use FontAwesome instead of Bootstrap's glyphicons.

Re-format HTML to my standards as has consolidated working on several projects
and move all modals outside footer.

Insert JS at the end which improves page load time.

Social modal is now gone.  Twitter, and only Twitter button is shown in the
footer (we have 41 tweets now). Thus removing store.js.

Use spinner from font-awesome. Remove jqyery.spinner.js. Needs polishing.

TODO:
0. spinner needs polishing.
1. BLAST buttons
2. notification stutters
