Extend environment file parsing to also parse environment.local

Browse Source 
This latter file can be created by the administrator next to the environment
file in order to override parameters set in environment file.
The reason for this is the environment file is always overwritten
during installation, while environment.local is never touched by
the installers. So making the changes in there ensures they persist
acros gnucash updates.
