Merge candidate

I think that this merge will deal with all pull requests but it's too late to be sure.

What seems to work:
 * Jpylyzer along with browser crashing ubuntu bug for invalid JP2Ks,
 * Xcorrsound with test files, and 
 * Flint.

What no longer works:
 * Pagelyzer but Zeynep's new demo HTML and JavaScript do work and the bootstrap setup has got lost.

Status unknown:
 * Matchbox is untested but the current state of the web demo is unknown.
