- remove empty useless HACKING
- remove unused cppcheck.sh
- migrate the AppImage docs to the wiki (which doesn't moan about licensing)
- try a HTML-style comment in the RELEASE docs
- Fix typo in the build-debugging bits
- Increase tmpfs size of /build because it looks like "make install"
ends up filling the disk, and then it fails.
- Make the Travis scripts a bit more verbose on failure
- Fix wrong filename tested for picking up the configuration
(this is why the builds were failing: missing the force-webkit
flag, while webengine isn't in the dockerfile for Travis)
