General:

• Restructured package (into a dedicated pynlpl subdir rather than root dir), removed patchy stuff from setup.py
• Updated installation instructions
• Added pynlpl.algorithms.possiblesplits()

FoLiA library:

• Updated for FoLiA v1.4.2
• Experimental text validation support
• always serialize XML with FoLiA version of library rather than FoLiA version from document; can't guarantee there are no changes
• text() method recurses in a semantically saner fashion
