This was already fixed with with https://github.com/fabpot/Twig/commit/6003ae43b92cfa7e1ddec17262733355e0bf435a but to make sure there won't be any regression bugs in the future. This is an edge case but the first and the last element of an empty string are empty strings too.
Before the above mentioned PR this threw a notice `Uninitialized string offset: 0`.

Refactor namespace/shortname parsing into own method

I've written a custom file loader in order for the namespace syntax to match across different resource loading classes. To achieve this I have to replace the loadTemplate method, which includes a lot of logic. While this logic may not be likely to change anytime soon, I'd feel better if the namespace parsing was extracted into its own method so I can replace just that bit.
