Switch import of config.py from import to exec

[novoid]

So far, lazyblorg.py is using import to read the configuration file. This might be changed to exec() for some reasons mentioned in https://lobste.rs/s/qyhvhc/your_configs_suck_try_real_programming#c_0btczk

[novoid]

Example: https://github.com/arp242/battray/blob/master/battray/init.py

So far, I don't understand all the code here with args:

def source_default():
    exec(open(self.default_config, 'r').read(), args)

args.update({'source_default': source_default})
exec(open(self.configfile, 'r').read(), args)
