Shift overflow bug #3702

clang is telling me:

init.cpp:782:41: warning: signed shift result (0x100000000) requires 34 bits to represent, but 'int' only has 32 bits

Git blame points the finger at:

82e96006 src/init.cpp      (Philip Kaufmann          2014-02-16 22:00:12 +0100  780)     if (nTotalCache < (nMinDbCache << 20))

Definitely wants to be an int64_t or similar.

As I said, I'm sorry... but I didn't introduce the shifts anyway.
