Version Control With Subversion Source

* www/es/1.1/: Remove directory. There exists no final 1.1 es translation of
the book at this time. This directory instead contained a mislabelled
snapshot of the es translation as of r1221, which was not linked to from
index.es.html in any case.
* www/es/: Remove now-empty directory.

Restore zh translation to trunk, after deletion in botched tagging operation!

Retroactively re-create zh-1.2-final tag with correct root.

Retroactively re-create zh-1.1-final tag with correct root.

Remove erroneously based zh tags to recreate properly.

* www/it: Remove empty directory.
It shall be re-created when we have a tagged version to publish in it.

* src/tools/bin/nightly-svnbook-build: Cron runs with minimal PATH. Compensate.

* src/tools/bin/nightly-svnbook-build: Add the actual nightly build invocation
script to version control.

Tweak tools ignore pattern to include 'fop-*' to allow keeping a versioned FOP
directory in the tools directory.

* src/tools/ (svn:ignore): Add 'fop-*'.

Remove grepping-out of [ERROR] lines from FOP output. Masking errors seems
like a bad idea to me, and the quantity of errors is minimal compared to
the rest of the noise that FOP produces.

* src/tools/bin/run-fop.sh
