Troubleshooting QuickLook on Mavericks

The QLStephen QuickLook plugin stopped working on Mavericks. Turned out it was quite old and hence wasn't 64-Bit code as seems to be required with Mavericks for QL… so I had to recompile it. While I was at it, also compiled a QuickLook generator for Markdown files and downloaded and installed Suspicious Package - neato.

Debugging issues with QL isn't too hard - use

$ qlmanage -p /path/to/file/for/which/ql/doesnt/work/anymore

to troubleshoot it.
