filter: load filter presets from XML files

This is a bit painful: since we don't want to modify the filter
presets when the user imports (as opposed to opens) a log,
we have to provide a table where the parser stores the presets.
Calling the parser is getting quite unwieldy, since many tables
are passed. We probably should introduce a structure representing
a full log-book at one point, which collects all the things that
are saved to the log.

Apart from that, this is simply the counterpart to saving to XML.
The interpretation of the string data is performed by core
functions, not the parser itself to avoid code duplication with
the git parser.
