Removed non-existent files from JS style tests.
Adding more complete list of JS style testing files
Added a trick to ignore the error code from the "pip uninstall tangelo" step.

The uninstall step is necessary because pip is a bit weird about reinstalling an
updated package - it doesn't always overwrite the old package.  This way is a
compromise between using --force-reinstall, which reinstalls all dependencies
from the network, and risking non-reinstallation altogether.
Removing js files that don't need to be tested (i.e., third-party libs)
Made all variables in web content scaffold "javascript style".
Collecting all testing "metadata" in an object to pass to testing function.

Closes #275
Bringing most JS files up to JSLint standards
Standardizing JSLint headers for web content tests.
Brought phantom scripts up to JSLint standards.

Resetting control panel height on collapse - Fixes #227

This takes care of changes that could happen to the control panel height
dynamically. Would not handle the case where the control panel is changed
while collapsed, not sure how that could be taken care of.
Improved the solution, and added a test.

Instead of statically saving the previous height of the element, we now
recompute it as it is needed.  This is done by removing any height directive
that may be on the element (e.g., if it is collapsed), computing the resulting
height with jQuery, and then re-establishing the height directive.  During
transitions, this computed height is used as the target height, and then the
height directive is removed (for open panels).  This way, whenever content is
added to the control panel, its appearance will be correct.  For open panels,
there is no constraining height directive, so the panel will re-render
immediately to its new height, while for closed panels, the height will be low,
but then a freshly computed new height will be used when opening.

This commit also adds a web-content-test to test the correct behavior.
