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.

If the git found is a shim, we need to follow the path to the actual git
directory to set the GIT_INSTALL_ROOT variable.
This happens when installing git via scoop for example.
## Rename user-profile.* user_profile.* to resolve#1806, #1675
* This is a backward compatible fix and will automatically and silently rename users '%cmder_root%/config/user-profile.\*' to '%cmder_root%/config/user_profile.\*' and '[user_specified_config_root]/user-profile.\*' to '[user_specified_config_root]/user_profile.\*' if the sources exist.
* Cmder.exe does this for cmd.exe sessions.
* The init scripts for bash and Powershell handles it for these shells
