Note that fetching any title besides the one for the current page is
considered "expensive". It also records the title fetched in the
ParserOutput so it will be listed in pagelinks, just like #ifexists.
This also moves the ToString test formatter into TestFramework.lua, so
TitleLibraryTests.lua can use it too.

It's easy to forget a 'local' somewhere and accidentally leak a global
variable. Add a unit test to catch that.

The existing unit tests work, but the setup is really not amenable to
the addition of additional tests in a modular fashion. This splits
things out so there is a framework for tests in Lua, and all a module
has to do on the Lua side is supply a list of functions to call and
results to expect. And then on the php side, only one array entry and
two short functions need to be added to LuaSandboxEngineTest to run the
tests.
