You can now add a key 'filters' in the preferences file that points to the
path of the filters file. If this key is not found in the preferences,
the default location '.duplicacy/filters' is used.
There is a new option '-filters' for the set command that set this key in
the preferences, but you can also edit the file directly.
Do not "misuse" property nobackupFile to trigger this feature.
- Restructured ProcessFilterFile function and splitted it in smaller parts.
- Prepare usage of new filter syntax for arguments of restore command.
- Using @<filename>, you can now include other files. Relative paths are supported.
This is useful, if you have several repositories with some different filters and a common filter base set.
Directories containing a file with this name will not be backed up. I find it easier to drop a .nobackup file in directories I don't want backed up instead of maintaining a file of exclusions. This is also useful for scripts that create data in the repository but don't want it to be backed up.
