Binary reader cannot read big files (>2gb)

[unitycoder]

Should add automatic switch for alternative binary reader, if file is too large.

added warning for now, until have some solutions

ok, +2gb files now work for animated .bin files (not yet released to store)
*now in store, so can load bigger animated.bin files

[unitycoder]

new format v2 can read +2gb files, BUT maximum is still around 177m points per file.
(and then next limit is c# max array size..)
