font-patcher: Allow to specify more options in config file

Browse source 
[why]
At the moment we have two different config files:

config.cfg:
Is read by gotta-patch-em and allows to specify some needed
commandline options for a font-patcher run

config.json:
Is read by font-patcher and can contain ligature table removal
instructions

It would be nice to combine/unify them.

[how]
Add the possibility to add commandline options in the config.cfg
file. Of course we need commandline options to specify the config
file first, so the options are parsed in two steps.

The config.file takes precedence (if possible) over directly specified
options.

This is how the new section in the config file can look like:

[Config]
commandline: --powerlineextra --mono
