Debugging and profiling

There are two recently added tools that can help OpenObject developers, debug() and @profile.
If you insert debug(variable) somewhere in your code it prints the variable name and contents to the server console. To use it, you have to 'from tools.misc import debug' and start the server with '--log-level=debug'.
Profiling measures method and function execution times. Look it up in the Python Standard Library. 'profile' should be used as a function/method decorator but unfortunately I don't know how to make it work yet...
