User options

[sde1000]

At the moment all the data we store about users is set by "the system" or "the management":

• Name and short name
• Web username
• Are they enabled?
• Are they a superuser?
• What's their current (register, transaction) tuple?
• A message to display on their next visit
• What groups they are a member of (and by extension, what permissions they have)

It may be useful to have some space to store options that can be changed by the user, for example:

• Left or right-handed (eg. for touchscreen)
• Colour scheme
• Level of help given (turn off extra prompts once they are no longer needed and have become annoying)
• Text size (and other accessibility options)

There may be more!

Perhaps (yet another) key/value store attached to users?
