Some language string mistakes / typos:

- two verbs in the following sentence: "The script to execute to run the Scheduler from the command line is"

- missing word "to" in "The webserver user is not allowed execute this script."

- the message is misleading in Windows and should be removed for Windows: "The webserver user is not allowed execute this script."

- wrong indentation in the file mod1/index.php in line 364 (starts with $dateFormat )
