Add command line execution support (Test Script)

[ThinkingEngine-net]

• Run script or test plan from command line.
• Select browser/execution options from the command-line.
• No UI mode - fails if UI/input (non-selenium) Gherkin commands are used.
• Update gherkin statements for compatibility.
• Output a text log - specified filename
• Output status in the command line.

Parameter management written:

• execute:<script> = Execute the script/project named "script"
• output: = Output the results of the execution as test to the file specified (also outputs an .html version and a .rtf version if tests complete)
• testplan: = The test plan in the project to run.

Execution of scripts complete:

• Minimises UI
• Loads script
• Compiles Script
• Disables UI elements in test scripts.

Need to add function for projects/test plans.
