Added symbols. (sort of)

strcmp is comparing more than just everythimg up to the '\0', so it's
very buggy.
Updated .gitattributes
Commented code.
Updated ar flags.
Added sylph_error function.
Finally fixed the Problem.

After hours spent debugging and rewriting the code, I realized that
`sylph_setlocal` contained `state->sym_reg.global` instead of
`state->sym_reg.local`.

Derp.

Now there is an "out of memory" error.
Nothing seems to be affected by it, though.
Removed changelog.
Got rid of the error, Microsoft style.

Commented out the error message.

(I'll fix it later.)
Added version information.
Updated documentation.
Updated .gitattributes
Added doxygen.
