Fixed some potential errors in sym-link generation, stepped through the create_symbolic_links function in utils.py and wrote new descriptive comments to sort out the operation of the function.
Removed group analysis' dependency on sym-links generation to run. Output files and QC files paths written to the usual .txt files in path_files_here and qc_files_here now, whether or not symlinks generation is enabled.
Fixed the GUI 'test config' file checks bug where input paths would be checked even if their associated workflows were turned off.
Resolved some symlink dictionary errors, cleaned up some code for 0.3.7.
Some minor cleanup for 0.3.7.
