Install: <module>_installer::install() is called, any necessary tables
are created.
Activate: <module>_installer::activate() is called. Module
controllers are routable, helpers are accessible, etc. The module is
in use.
Deactivate: <module>_installer::deactivate() is called. Module code
is not accessible or routable. Module is *not* in use, but its tables
are still around.
Uninstall: <module>_installer::uninstall() is called. Module is
completely removed from the database.

run faster. This fixes ticket #235.
Incidentally, refactor exif and search to use the same patterns
overall so that if you understand one, you understand the other and
they generally use the same strings for localization.
E.g. "%link_startClick here%link_end" is now '<a href="%url">Click here</a>'.
Note: This isn't always the best solution. E.g. consider "Foo <a href='%url' class='gDialogLink'>bar</a>." Now the translator has to deal with
preserving CSS classes too...
