Bugfix release 2.1.6

[Sergey Basalaev]

This release fixes bugs which are quite serious and it remains mystery for me why they were unnoticed for so long.
Bugs fixed in this release:
* Hexadecimal character literals (like '\u03C0') were parsed incorrectly by compiler
* asin() and atan() functions returned incorrect values

Since GoogleCode stops supporting new downloads, Alchemy OS can now be downloaded from SourceForge.

Thanks, Sergey!
Just wondering, though. How did you notice the problem with atan() and
asin()? Doing some trigonometry? :)

While refashioning core libraries for the next major release I've decided to
test how accurate my implementations of math functions are and found
out that the maximum difference between my atan() and Math.atan() is
about 0.26 - VEEERY inaccurate. asin() and acos() are both computed

using atan() so they are also affected.

Great! When it comes to math, every degree of accuracy counts ;)

Yeah, usually error in the first digit is not what you expect.
