Add possibility to draw voxels as boxes.

The colors are set to be the same as the VDB paper, just like for the
tree. They are drawn perfectly, but that'll for the moment.

Msgfmt: Fix for generating .mo files from .po without comments

Report proper frame and time to the console when doing compositing

Cleanup, use define instead of magic number

Print elapsed time when rendering from the command line

Flush stdout prior of calling render stats callback

Without this extra flush order of stat prints is undefined in the
output. which makes it rather tricky to write custom output in a
reliable way.

Move draw settings to its own struct and add some more options.

For now the options control the tolerance for drawing voxels and their
size in the viewport.

Cleanup: get rid of ugly bool in structs, replaced by bitflags.

Make selection & co really working even during listing process.

This commit replaces `filelist_numfiles()` by `filelist_files_ensure()`. The later
also returns number of visible files (i.e. filtered ones), but also ensures filelist
is filetered and sorted.

Otherwise, during listing process, operators could be executed between an update of the listing job,
and the refresh from the file space - i.e. at a time filelist is virtually empty (from filebrowser PoV).

Also, got rid of 'need_refresh', this ended up being unused...

Selection/UUIDs handling enhancements:

* Do not systematically clear selection_state's uuids GHash when updating filelist
during listing process - uuids used here should remain valid.
Allows to not lose selections during listing background job!
* Use new BLI_ghash_lookup_p to handle selection state setting, symbolic optimization but...

Make imbuf_thumb for .blend a bit less stupid & noisy regarding missing previews.

A file which does not have *any* preview is perfectly valid, error is only when there
are some previews, but not the same number as actual datablocks...

Fix some fileops operators that could try to get out-of-bound indices.

Also, some minor reordering in full-block-recaching, currently could not create
issues but better be safe & logic here.
