[Evolution-hackers] libical import

[Hans Petter Jansson <hpj ximian com>]

I believe I've addressed most of the build issues with the new libical
now. It should build nicely out of a clean checkout, but you'll need
Flex 2.5.31, available from http://lex.sourceforge.net/ if you're
compiling from CVS. I've removed the generated files.

Sorry about the high version requirement - since Flex is changing
rapidly, and libical needs some functionality from Flex 2.5.7, we could
either require flex == 2.5.7 or flex >= 2.5.31 (with some fixes I made
to libical).
