git-remote-mediawiki: scripts to install, delete and clear a MediaWiki

install_wiki.sh allows the user to install a MediaWiki instance in a
single shell command. Like "git instaweb", it configures and launches
lighttpd without requiring root priviledges. To simplify database
management, it uses SQLite, which doesn't require a running daemon, and
allows reseting the database by simply replacing a single file. This
allows install_wiki to also defines a function wiki_reset which clear all
content of the previously created wiki, which will be very useful to run
several indepenant tests on the same wiki.

Note those functionnalities are made to be used from the user command
line in the directory git/contrib/mw-to-git/t/
