fix whitespace issues Includes fixes for the following whitespace-related issues: - Trailing whitespace at end of line - Tabs in file - No newline at end of file This commit fixes these issues for .rb, .coffee, and .sass files.

Checkout files in a shared directory. Otherwise they get lost with each deployment and have to be reparsed with Hets.

refactor xml-file questions for rails style.

add pp_xml_name and xml_name and set them While parsing we set the pp_xml_name and xml_name to avoid confusion when determining the name ourselves.

move proper encoding function to class string

set encoding to UTF-8 before sending file to hets

add method to determine code reference path Since we now generate Codeposition files with the -o pp.xml option of hets, we will need to determine the path to that file.

fix seeds: child ontologies don't have an own raw file

prepare for codemirror

fix ontology upload type-error

All unit tests running
