Script input fields should support syntax highlighting for Windows and Unix shell

Current Situation

• Multiline script input fileds for jobs, pre- and post-processing monitors etc. support syntax highlighting if the languages Java, JavaScript or PowerShell are used.
• No syntax highlighting is supported for shell commands used with Windows or Unix

Desired Behavior

• Syntax highlighting should be supported for Unix shell (bash) and for Windows shell
• If a line exists in the script that starts with # then Unix shell syntax highlighting is applied, otherwise Windows syntax highlighting is applied.
