Code improvement - 4 - tags, and negation

I have taken a few more days to keep improving the syntax. And it really feels more comfortable now.

To make it short, there is now a tag system. It will choose at random any line which correspond to a Variable Name which has been created.

#Start
    *moon/?CheckTagExist()
    *sun/?CheckTagExist()
    ?CheckTagExist()
 
?CheckTagExist()
    moon : A moon has been created
    sun : A sun exists
    Neither the moon, nor the sun have created

Possible results :

A moon has been created
A sun exists
Neither the moon, nor the sun have been created

Plenty of other small improvements have been added too (more efficient commenting, better uppercase handling...)

I am happy with the way TextStew is, now. I might still add an improvement with files handling (to nest them in directories). But I might publish a version soo,

Now, it is time to go back in the investigation of Electronic Poetry !
