Latte Engine: MultiPath Support

[alexander-schranz]

Currently Latte Engine does not support multiple paths inside a project. Which make it hard also used by third party libraries. There is currently open pull request which should change this so multiple paths should be able to be used by a single instance of Latte:

• [Feature Request] Support for multiple paths nette/latte#314
• Add namespace loader nette/latte#320
