Keep information about all block files in memory
Parameterise command line option defaults, so translations are independent of them
build: quit abusing LIBS for Windows builds.

Similar to the INCLUDES changes in 6b099402b40, split out LIBS into individual
entries for more fine-grained control.

Also add MINIUPNPC_LIBS which was missing before, and hook it up to
executables.
Bugfix: Remove default from -zapwallettxes description (inaccurate)
build: fix libtool's refusal to link static libs into a dll

Merge src/leveldb changes for LevelDB 1.18.
Add a SECURE style flag for ThreadSafeMessageBox, which indicates that the message contains sensitive information. This keeps the message from being output to the debug log by bitcoind. Fixes a possible security risk when starting bitcoind in server mode without the 'rpcpassword' option configured, resulting in the "suggested" password being output to the debug log.
Add buildenv.py to gitignore
script: move CScriptID to standard.h and add a ctor for creating them from CScripts

This allows for a reversal of the current behavior.

This:
CScript foo;
CScriptID bar(foo.GetID());

Becomes:
CScript foo;
CScriptID bar(foo);

This way, CScript is no longer dependent on CScriptID or Hash();
script: add ToByteVector() for converting anything with begin/end

This should move to a util header once their dependencies are cleaned up.
script: move ToString and ValueString out of the header
script: add a slew of includes all around and drop includes from script.h

Lots of files ended up with indirect includes from script.h.
