Parser Enhancement: Fallback to Folder name (#129)

Browse source 
* More cases for parsing regex

* Implemented GetFoldersTillRoot for falling back on parsing when we can't get anything from the filename.

* Implemented a fallback strategy. Not tested on large libraries yet.

* Fallback tested and working great.

* Removed a test case that won't pass and added some trims
