Adapt DocManager with Configuration File

[tomschr]

As more and more ideas and wishes are implemented, the need to have a configuration is also more and more important. A configuration file could be used to define aliases or standard options, for example.

The DocManager configuration file can be searched in these places:

• /etc/docmanger3.config (as a global file; do we need that?)
• ~/.config/docmanager3/config (as a user configuration)
• .dm3.config (in the current SVN/Git repository)

Preferred module is configparser.

The user home config file will be now created if it's not exists: https://github.com/openSUSE/docmanager/commit/1288956f2e20ac14a5ecd38595c9267b818cdec4

We can improve it later after the 3.0 release.

Excellent! :+1:

@tomschr Do we really need a global config file and a config file for each repository? I'm not against it but we should decide it for the next release.

Actually, this is a no brainer for us, very easy to implement. :smiley:

If we want it, we can pass a list of config filenames to the ConfigParser.read method. Filenames which cannot be found or opened are silently ignored. All configuration parameters are merged.

To find the config file in current Git repository, use:

git rev-parse --show-toplevel

Possible things to store in a config file:

• switch on/off colorizing
• aliases
