Warning about just released RC 5

From Dmitry Yemanov:
Windows builds of Firebird 2.0 Release Candidate 5 have been released with an issue related to the INTL support. This is not a bug in the code, but a build/packaging issue. One of the ICU libraries (icudt30.dll) got built wrongly. We apologize for inconvenience, the builds are to be fixed and re-released shortly. In the meantime, icudt30.dll from the RC4 package would fix the issue.
