added functions to main class

*This might have been doable already but I couldn't figure out how
without editing the source script*.

I added most of the helper functions to the ADMINCON class so that they
can take advantage of the local connection properties. This makes the
class callable from other scripts without editing the source. e.g.

import AdminFunctions
con = AdminFunctions.ADMINCON('ddowling','PW','myserver',6080)
services = con.getServiceList()
folders = con.getFolders()
services = con.getServiceList()
con.stopStartServices('Stop', services)
check token in between service stop/start calls

If there are many services and the time between stopping and starting
them is long then the token can expire. This calls the method to check
token validity between service start/stop calls and refreshes if it has
expired.
