ND2 - Bug fixes

1)
All ND2 files are unicode and RandomAccessInputStream is UTF8 by default.
Reading String until null byte.
"\0" -> "\0\0"

2)
ND2 Structure Level:
When you read the length of the level, is relative to the begining.

3)
Numerical Aperture changed name

4)
New TextInfo will be in "Lite Variant" not in XML. We will also be droping XML structure.
Added functions to "move" metada from global store to the ND2Handler
