Don't warn about forks while fIsInitialDownload

[TheBlueMatt]

This is a cheap hack to address the warnings people get during initial download, feel free to discard in favor of something more reasonable.

Automatic sanity-testing: FAILED BUILD/TEST, see http://jenkins.bluematt.me/pull-tester/c35d9c0952c41af08c48aab907d3aae1a2d8ee10 for binaries and test log.

This could happen for one of several reasons:

1. It chanages paths in makefile.linux-mingw or otherwise changes build scripts in a way that made them incompatible with the automated testing scripts (please tweak those patches in contrib/test-scripts)
2. It adds/modifies tests which test network rules (thanks for doing that), which conflicts with a patch applied at test time
3. It does not build on either Linux i386 or Win32 (via MinGW cross compile)
4. The test suite fails on either Linux i386 or Win32
5. The block test-cases failed (lookup the first bNN identifier which failed in https://github.com/TheBlueMatt/test-scripts/blob/master/FullBlockTestGenerator.java)

If you believe this to be in error, please ping BlueMatt on freenode or TheBlueMatt here.

This test script verifies pulls every time they are updated. It, however, dies sometimes and fails to test properly. If you are waiting on a test, please check timestamps to verify that the test.log is moving at http://jenkins.bluematt.me/pull-tester/current/
Contact BlueMatt on freenode if something looks broken.

Seems reasonable...

This will hide the warning, but is that the entire problem? will the block chain download continue?

[TheBlueMatt]

The warning doesn't effect the download at all, and is generated sometimes when a "fork" is detected because we get blocks while we were in initial download.

ACK in that case
