[JW Lua] 4 new sample scripts

[Jari Williamsson]

Hello!

I have added 4 new sample scripts to the Wiki's "Quick Scripts" page:

* "Double Precision Time Signatures" - time signature editing
* "Open File Names" - how to work with the dialog boxes for file/folder 
navigation
* "Break Secondary Beams" - a beam breaker script
* "Mute Selected Staves" - how to work with the staff selections and 
Score Manager info.
