Have "Save" and "Restore" buttons in both the tool preset list/grid
and the tool preset editor. The save button stores the active tool's
options in the preset, if possible.
Commit c4bb708 was making `make check` fail. I should not return `false`
on the .pot file generation, simply warn. I explicitly fail the `make
update-po` command though when $(INTLTOOL_UPDATE) is the `true` command
because I know the message merge will fail and there won't be any proper
error message explaining why when it does.
Commit c96006919 worked around a still-existing bug (well at least the
bug report is still open) of intltool with automake 1.15 when the build
and source directories are different (VPATH build) by replacing
`intltool-update` by `true`. But because of this `make update-po` fails
on such a build and the make output is totally unclear at why. Add an
error message when this happens.
"There is one image" should not necessarily be translated to '1' in
other languages. It depends if their singular applies only to 1, like
in English. For instance in French, it can also apply to 0, so I fixed
the French translation.
"dépôt" is not a proper translation for "commit".
"Modification" seems more appropriate, though the Pro Git book (which
is a reference on the topic) keeps the English word "commit" even in
the French version (simply italicized when in a sentence). But let's
use a French word for now.
