Add /f for fast init.

[daxgames]

The below enables Cmder Fast Init mode for cmd.exe sessions. This is more like the Cmder 1.3.5 init process. See issue #1821

Cmder Fast Init mode bypasses or disables the following Cmder 1.3.6+ features:

• Git root and version detection. Defaults to %cmder_root%\vendor\git-for-windows if it exists.
• Path enhance validation before path modify so %Path% enhancements are forced.
• Recursive path add for "%CMDER_ROOT%\bin"
• Recursive path add for "%CMDER_USER_BIN%\bin" if /c [user_config_folder is specified.
• /d switch to enable debug output.
• /v switch to enable debug output.

Add /f to Cmder task as shown below t enable fast init:

Note 1: This setting is invalid in Cmder Powershell and Bash sessions~

Note 2: Add /t also to see init timer output

Cuts ~2.4 seconds off of init time.
