Fix

- Fixed - loading of properties files ( using reversed \ ).
- Fixed - loading of files or htmls with URL object. Added suffix for a
file version.html.
-  Changed - versioning is in string format.
- Fixed - reading lines in method getData now appends newlinecharacters
- Fixed - file structure. version and history tags are separated by
release tag => more splitting and parsing (firstly by tag release
secondly by newline character). One release should have version and
history tag but it's not essential. Version tag is sufficient.
- Fixed - correct parsing of version.html files.
