Fix definition of ssize_t and off_t.

Service install with a full path to the conf file was failing. Part of this was due to not passing quotes along with arguments with spaces. The other part was not adding access allowed ACEs on all accessed paths.

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

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 #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 #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 preshutdown notification support to service to deal with Issue 87. Also improved message filter support for eventlog.

Added support for redirecting Redis logging to the Windows Application log. Repurposed --syslog flags for this. See redis.windows.conf for information about the repurposed flags. When redis is running as a service it will use the Windows EventLog by default.
