Rename <LibraryName>_EXPORTS for CMake

[paroga]

Is it possible to rename all <LibraryName>_EXPORTS to Poco<LibraryName>_EXPORTS? If you do so, additional definitions won't be necessary when building with CMake. Maybe you should also consider renaming <LibraryName>_API to Poco<LibraryName>_API to prevent naming confilcts.

Crypto_EXPORTS -> PocoCrypto_EXPORTS
Foundation_EXPORTS -> PocoFoundation_EXPORTS
...
Zip_EXPORTS -> PocoZip_EXPORTS

Maybe for 1.4 (the version currently in the SVN trunk). And only if someone commits to updating ALL source and project files. And only after the 1.3.6 changes have been merged back into the trunk (which won't happen before January).
