Allow a theme lang file

[Robert Lyon]

Sometimes a theme may have a homeinfo.tpl file that contains hardcoded lang strings.

But there is no relating lang file to make things easy to translate.

So I've got the system to check for a theme language file.

As described in the commit header, to use it in a template you need to indicate the section is a theme by
going:

 {str tag=stringtoget section=theme.nameoftheme}

... and this will look for the lang file in: theme/nameoftheme/lang/langtype/nameoftheme.php

We need to make sure that this works with external langpacks and with /local lang overrides. It looks like it works the same way that plugin lang strings do (by adding to a set of search paths that get_string() uses) but we should explicitly test it.

Language-ifying the strings in the primary school theme (Bug 1362871)

Currently there is no way for themes to come with their own language
files - but sometimes a theme may have some text it wants to display
that is unique to that theme - like when it has a homeinfo.tpl file

I've added the checks to the lang path for checking a theme's lang file

To use it in a template you need to indicate the section is a theme by
going:

{str tag=stringtoget section=theme.nameoftheme}

and this will look for the lang file in:
./theme/nameoftheme/lang/langtype/nameoftheme.php
