Interception of incomplete commands

[Sheridan]

The bot engine intercepts incomplete commands. For example, if you pass a command /g to the hello-bot, it will react as if it were passed to /greet

[zmeyc]

This is intended behavior. For example instead of "zone list" user can type "z list".
They're also supported in subcommands, i.e. router["zone list"] = f() will also react to "z l".
Probably we need a flag to optionally disable abbreviations.

Yes, we need a flag, because many still remember IRC and write /me .... If the bot has a command /menu, then it call :(
