Version 0.3.9 rc1, please test

Here's a test build if you'd like to help test before 0.3.9 is released.
(or if you'd rather get upgrading out of the way now instead of waiting)

Unfortunately we don't have an official changelog yet (except for the SVN revision descriptions).

Here is my unofficial changelog:

• fix: makefile.osx
• change: enable SSE2 in 64 bit builds
• change: connection rules
  - always make 8 outbound connections
  - only one connection per a.b.*.* range
• add: switch "-maxconnections=#" (discussed here)
• change: JSON-RPC API prints floats with 8 decimal places
• change: "bitcoind help <command>" instead of "bitcoind <command> -?" (based on a patch by jgarzik)
• add: JSON-RPC "gethashespersec" (based on a patch by lachesis)
• add: "version" and "hashespersec" fields in JSON-RPC "getinfo"
• fix: "-datadir=<path>" with relative path (bug described here)
• change: autostart disabled by default except on Windows (requested here)
• fix: occasional "vector iterator not dereferencable" assertion when compiled with msvc
• fix: readlink compile warning on Linux build
• fix: BSD detection (bug described here)
• add: "-paytxfee=#" switch (explained here)

Please tell me if you know of any other forum threads discussing the bugs/changes so I can add them to the list.

Don't wanna take credit where it's not due

the hashes/sec patch was from lachesis, and the extended-help might have been based on my idea, but the code was somewhat different.
