Introduce monitor(), install module deps and search for module datasets

[TimKDJ]

Worked on this quite a while ago; the intention was to introduce column encoding, but I'm not sure I'll get around to it, so I figured I'd at least get this out.

• Deprecates setPkgOption("module.dirs") in favour of monitor()
• Introduces setPkgOption("install.deps") so missing deps are installed automatically
• Now also looks for datasets in modules (fixes runAnalysis csv file location #18)
