Pass jshint

Ignore third party file modules/qrcode.js

Fix the few other errors:

modules/jquery.qrcode.js: line 47, col 10, Missing semicolon.
modules/jquery.qrcode.js: line 63, col 2, Mixed spaces and tabs.
modules/jquery.qrcode.js: line 81, col 10, Missing semicolon.

And clean trailing whitespaces while at it.
