if "redis-server --service-install config.conf" and the .conf file had an include statement, then "redis-server --service-start" would fail because the current directory was set to %systemdir% on startup. Changed the current directory to the executable directory when --service-run is encountered

issue 123: changed error output in Win32_service and Win32_QFork to use redisLog. Also fixed a few compiler warnings.

issue 119: error reported in sentinel.tcl testing. Error expected. Moved output to loglevel verbose.

Issue 120: sentinel reporting error writing to config file. open(O_RDONLY) followed by fsync() would result in access denied error in windows. In the context of the code changed, ifdefing out fsync on Windows was the safest thing to do.

issue 105: 32-bit version not running on server 2003. Adjusted project settings and selected APIs in use via runtime version checks and windows version macro.

issue #93: cleaning up memory mapped files left over in cases where FILE_FLAG_DELETE_ON_CLOSE will not clean up file

issue #112: Adding permission for  NETWORK_SERVICE on the folder redis-server.exe is in during --service-install.  This allows for RDB files to be written and for .conf files to open in RW mode. Fixed a documentation typo.

Issue 108: Added 32-bit support back in. QFork code requires a contiguous memory allocation for heap. Due to this requirement and 32-bit memory model limitations, maxheap is limited to about 512MB in 32-bit executable. 32-bit version appears to be about 30% slower than 64-bit version on 64-bit OS.

issue 99: adding sample to demonstrate config of master + 3 slaves + 3 sentinels on one box. Discovered along the way that maxheap would not propagate through .conf include statements. It does now.

fix for issue #97: Added a modified sample to demonstrate large async GET operation. Also discovered that reply reading in async.c would stop if the reply data exceeded the buffer allocated for the read. redisAeAddRead() would not reschedule a read if already in read mode. To fix this is added redisAeForceAddRead().

Issue #95: Adding ability to specify custom service name/have multiple Redis service instances running.(Forgive the whitespace changes in Win32_Service.cpp. My editor was set to keep tabs when I wrote the code originally. Tabs are gone now.)

Added support for SIO_LOOPBACK_FAST_PATH (http://msdn.microsoft.com/en-us/library/windows/desktop/jj841212%28v=vs.85%29.aspx) . This speeds up localhost performance on Win8/Server2012+ significantly. In order to take advantage of this clients will have to enable socket fast loopback before connect().

The internal HLL raw encoding used by PFCOUNT when merging multiple keys
is aligned to 8 bits (1 byte per register) so we can exploit this to
improve performances by processing multiple bytes per iteration.

In benchmarks the new code was several times faster with HLLs with many
registers set to zero, while no slowdown was observed with populated
HLLs.
