[AgileWiki] arguments on AwServer

[Bill la F. <bil...@su...>]

I've just barely started the rebuild facility--it will be invoked by a 
command line argument when running AwServer.

AwServer now takes a single argument,  which can be any of the following:

*no arguments* - a normal run
run - a normal run
clean - deletes all but the .wdbr files
new - does a clean & run to create an all-new database
rename - renames the .wdbl files to .wdbr
rebuild - create the database from the .wdbr files

Of course, the last option does not work yet!!!
