Rules update

As I've mentioned a few times, Rainworld began life, conceptually, as a slightly streamlined retroclone of SLA Industries 1e. This has always been especially visible in the skill list, which always had some of that essential 90s "too many skills" flavour, along with a dash of "some of these are useless, and some of these are overly useful".

Rainworld today is a long way from those roots, and the skill list is honestly one of less usable parts of the system. Today's update does two things:

• replaces the 1-Handed Melée Weapons and 2-Handed Melée Weapons skills with a single Melée Weapons skill, and
• removes the Gear Maintenance skill entirely.

(There are also the usual typo fixes, etc. — the Flow Techniques prerequisite diagram no longer has Nonlocality labelled as Illuminosis. Oops.)
