l10n/it: update to latest messages.pot

wiki: Apply `[wiki] split_page_names` to internal free links and relative links when no explicit label is given.

Part of #9239.

wiki: Added the possibility to have `["internal free links" with a label]`.

Also consistently accept a `?query=string` where a `#fragment` was accepted. This was already the case in most of the link syntaxes, but a few special cases were missing.

Closes #7695.

Makefile: switching `make coverage` to use Ned Batchelder's excellent [http://nedbatchelder.com/code/coverage/ coverage.py] system, instead of figleaf.

The (non working) figleaf rules have nevertheless been kept (`make figleaf` et al).

coverage.py has no problem with doctests and the generated output is much nicer.
The problem with with functional tests is still not solved though (probably due to server exit condition).

You can also take benefit from advanced coverage feature by setting the `coverageopts` variable, e.g. `make coverage coverageopts='--branch'`.

Makefile: fix the PATH, on Windows.

mimeview: Fixed the rendering of GIT patches where binary files are added or removed.

Norwegian translation 'nb' almost complete. A few terms remain untranslated, as well as some longer trac-admin output.

Always 'information', never 'informations' in English.

Integrate first batch of TracGuide changes, in preparation for 0.12beta1

Makefile: reworked `coverage` target.

The coverage tool is still [http://darcs.idyll.org/~t/projects/figleaf/doc/ figleaf].

**Note that this is work in progress, figleaf doesn't work as expected yet, due to the presence of doctests, apparently.**

A few things were adapted so far:
- `doctest.testmod` was badly interfering with figleaf, making the latter believe nothing happened after the `testmod` line (which was not true as the suite did run)
- once `doctest.testmod` was no longer used, the `del __builtins__._` needed for ''Clean up after doctest or spambayes gets unhappy'' was no longer working and needed I suppose; removed it
- added the exclude pattern `\\lib\\`, useful on Windows
- no idea why, but running
{{{
FIGLEAF=figleaf python trac/tests/functional/testcases.py -v
}}}
worked, while
{{{
FIGLEAF=figleaf python trac/tests/functional/__init__.py -v
}}}
did not, on the command line - this is still not working from the Makefile?

Then, some niceties:
- added a `clear-coverage` target to remove stuff generated by figleaf
- added a `show-coverage` target to generate the HTML files showing the coverage for *.figleaf files generated up to now (and the files go in the `figleaf/` folder instead of the `html/` one)
- added `unit-test-coverage` and `functional-test-coverage` targets to build the coverage data for unit tests and functional tests respectively (`test-coverage` to do both)
- `make coverage` does a `clean-coverage test-coverage show-coverage` cycle
