wxgui: maps ordered using "natural sort"

[pmav99]

I think that it would be really useful in the GUI to get the maps to be ordered using natural sort[1]. This would be particularly useful in tools like g.gui.animation where you have to manually order the maps if they are named with an integer suffix. For example, now, if you have these maps:

map_1, map_2, ..., map_10, map_11, ..., map_100, ..., map_200

when you try to add them using "multiple add" you get something like this:

map_1, map_10, map_100, map_101, map_102, ..., map_19, map_2, map_20, map_200, map_21, map_22, ...,

and this is not usually the animation you intend to create.

Other places where I think that this functionality would also be useful is things like Map Layer in the wxgui and also g.list.

WRT to implementation, in python there is the natsort package[2] which is by far the most flexible solution, but it is rather trivial to implement a subset of the package's functionality on your own (e.g. [3] and [4]).

Implemented in r67070 with one of the simple implementations. Map selection widget and Add multiple maps dialog are using it. Please test.

Replying to neteler:

pmav99: Can r67070 be backported, works?

yes, after release.

I just tried the patch on releasebranch_7_0 and it applies cleanly. The functionality is also working as expected.

Backported in 67774.
