Merge with #191 tricky characters for batch file

Fixing stx executable and double quotes - to work with path that has spaces in it
removing text colors - to speed up execution for non-logging case
SETLOCAL DISABLEDELAYEDEXPANSION for non-logging case
removing superfluous messages when logging is not used
adding %use_color% when no_logging is used considerable speedup
fixing timer at :time_in_seconds function to start correctly
adding a comment to note the timer section
changed version
In powershell reverted back to: $stx_switch = [environment]::GetEnvironmentVariable("stx_switch")
Adjusting documentation to fit new reality

    17251718ECHO 7) The launcher can have issues with double-quotes and quotes within - escape them when needed - e.g. use double double quotes to escape
    1726 ECHO 8) Issues with the "!" character to add it you have to use escape ^ character e.g. --eval "Transcript showCR: 'Bang^^^!'."
