[stellation-res] svcadmin: new (and soon to be only) way to initialize a

[Dave Shields <shields@xxxxxxxxxxxxxx>]

I've just added 'svcadmin', based on repos/Admin.java, to be used for repository 
administration:

  svcadmin initialize location file
  svcadmin initialize location user-name user-password

which performs the same function as 'svc config database'.
I have updated guide.html to include 'svcadmin' in the documentation
for 'configure database'.  For example, 
  svcadmin init postgres:mergetst shields my-password.

'configure database' is now deprecated, and will be dropped as soon
as all scripts that use it have been changed. I have so far only changed
the ant file used to run the tests, which should be now be run as
  ant -Dsvc=path-to-svc -Dsvcadmin=path-to-svcadmin 

As part of this edit, Location was moved from workspace to repos.

The reason for the change (suggested by Mark) is that 'configure database'
is a repository, not workspace, function, and it should not be part of the
command-line client. 

The build/bin now has script 'svcadmin', derived from new scripts/svcadmin.sh.
