Allow dragging and dropping query file into query sequence textarea.

All of the code is courtesy Clayton Wheeler (@csw) and Ben Woodcroft (@wwood),
(see #98) with very minor modifications from myself:
1. No need to dynamically position dnd-target-marker.
2. We already had a button to clear query sequences. Integrate with that.

Because of the recent frontend overhaul (including BS3 upgrade) it was easiest
for me to cherry-pick code, rather than merge csw:dnd or wwood:dnd branches.

Graph controls now handled by jquery.t.js itself.

The button click event listeners and the corresponding behavior are now
implemented in t.js itself, requring ss.js to call only one draw
function on the appropriate element.
