libs should be loaded after user configuration

In run(), because user configuration is loaded (step 4) AFTER the lib_dirs are required (step 2), the framework user can't easily change the lib_dir option in a useful way.

i.e. even if I change lib_dir in configure(), the libs in the new lib_dir are not loaded. I think that the typical user will expect that a change to lib_dir in configure will still allow lib_dir to be required properly.

I propose that the run order be changed slightly to accommodate:
1. set error handling
2. set user configuration
3. load libs
4. set default methods
5. check request
