[JW Lua] JW Lua beta 0.17 available

[Chris]

Thank you for the update (FCChord.Alteration for me)
Add you FCKeySignature ?

Otherwise I can create new staves but I can not create new TextBlocks 
for titles.

And for your information, international characters (for comments and 
titles of plugin) are not properly stored, they are replaced by another 
character.
(but not a problem for me)

Thank

Chris
