Portable BMU variable update

[Justin F]

Hiya,

I've just updated the ROOL documentation to add an new flag to the 
BMUVariable_Flags for 'BatteryFailed'. So I went to add it to the OSLib
file, and found that there's a few bits which can be updated, and a 
mistake.

So here's a diff... and the explanation...

* Comment added for teh reference to the BMUVariables, to make it clear 
  where the canonical source is :-)
* A bunch of new variables for the more recently defined variables.
* Fix type of 'BMUBatteryChanged' which should be 'BMUBatteryCharged' -
  if you've been using it to detect that the battery was changed, it won't
  be effective ('cos nobody ever used it for that). So the change in
  the variable name will cause code to break, which is fine because it'll 
  tell people that it's wrong.
* BMUFlags for BatteryCharging, which has been there a while, and 
  BatteryFailing, which is new.
* BMUCommands for controlling the BMUEvent which are apparently new
  according to the documentation.

These are now all the changes from the documentation, but just those that
were quick and easy to update.

I'm not sure how to create pull requests/merge requests for subversion, so
hopefully this patch is useful...
