Fixed async isues with index #91

The index runs async everywhere, it's kinda impossible to know which path with resolve first, so testing is hard. Sometimes a race condition is hit, well, it was. Now that map has a mutex on it.

Also fully fixed handling files with relative links. A basepath property has been added to the index configuration to allow a local root to be set when resolving files.

Added a full checkout test for digital ocean so that full remote and full local testing is performed.
