BUG Fixes:
* Removed recurse info from the label before int converting the ALT info.
* Make head pointer relative (rather than about), for new nodes, as the case for all spacy tokens.
* Added special treatment for '' symbol that appears as a preposition, since we use this symbol in the label as a separator.
* Replacing existing info that comes after the colon with new info, instead of adding it.
* Prevent more than one copy node per token for 'prep' expanding, as these causes infinite loops, and adding many wrong info.
* Fixed wrong coping of attributes (because of wrong inducing)
