Fix sequences with spaces in front causing BLAST to fail.

If the sequence query somehow contains blank spaces in the front, BLAST
program fails, and an exception is raised. Fix that.

Add chevron to indicate the collapsible nature of hits

Collapsible hits - change chevron style, use delegated event.

Chevron style now is black against white, and down and right. Older
white against black style was rather distracting, imo. And using
right instead of up makes the hit header look FASTA-ish when folded.

It must be noticed that fa-chevron-right class isn't used. Instead
fa-rotate-270 class is toggled on fa-chevron-down. This is because
fa-chevron-right and fa-chevron-down are of unequal width, and the
text in the header would shift on toggle.
