fix(compression): remove 'safe' compression from all resources

Fix https://dev.plone.org/ticket/13606: safe compression on big javascript
files. Just remove the compression on all resources, we already use
minified version

Merged from master.
Test this branch with Plone 4.2.x.

Not 4.3.
Use js bundle default.

On Plone 4.2 or earlier the bundles are not actually used.
