gpspm 3.1.7 passed the autobuilder, should reach the repository soon.

• 100% battery-friendly pause. It no longer drains 50 mA or so.
• Improved autopause reliability.
• Fixed (or at least made VBA-like) day of week reporting in RTC. I tried to find a reliable specification of real time clock from GBA cartridges (without success) and I am not aware of any licensed games that differentiate between days of week, so I am not sure which way to return current time is correct. However, there is a certain Pokemon hack (Liquid Crystal) which had a problem with gpSP's implementation, so I have changed it to behave like Visual Boy Advance.
