respect Trac permissions

[GoogleCodeExporter]

Describe the enhancement in detail.

Trac issues its own permissions to users which may limit which XML-RPC
methods are available to them. Currently, if a user isn't allowed to edit a
ticket but tries to use the edit command in TracShell, they will get a
xmlrpclib.Fault exception printed out which isn't helpful.

The enhancement proposes a way to check the available XML-RPC methods at
startup time and handle the issue gracefully in the shell. Either by
limiting which do_* functions are available or by warning the user and
avoiding executing the entire function.

What files will be affected?

tracshell/shell.py
tracshell/trac.py

How will the enhancement benefit the project?

It will make the program more usable and less prone to error.

What side-effects (if any) will the enhancement create?

None
