This currently fails.
This test is a reduced version of permission_mask template in acp, which
is not correctly compiled by the current template engine code.

phpbb_template_compile is now much simpler. It takes complete file paths
as inputs, either source template path or source template path and output
compiled template path. The number of methods also went down to two -
compile template and returned compiled text or compile and write to file.
phpbb_compile class is responsible for determining source and compiled
paths. It already had all the data necessary for this, now the code is
in the same place as the data it uses.

Do not change $recompile from true to false - any recompilation
condition alone is sufficient to force recompilation.
Also uncomment the nonexistent file test which passes with this fix.
PHPBB3-9726
Due to the usage of `__DIR__` for the file includes the tests can't
be ran on systems with PHP < 5.3. Replace all occurances of
`__DIR__` with `dirname(__FILE__)`.
