how many requests does the scanner make? if e.g. a couple low-risk requests (homepage, readme etc.) we can treat it as low risk

The PR is heading in a quite good direction! What seems missing (or I just don't see that) is:

• what is the meaning of moodle_version_found report? IMO we should report only if the version is obsolete. If that's the case, can we rename it to obsolete_moodle_version_found ?
• the possibility to set user-agent to the one Artemis is using
• does the scanner fail on websites with bad SSL? IMO it should not, the websites with bad SSL are often the ones with the most juicy findings :)
