Messages - Correlation property names need proper validation

[madhurrya]

1. When I have used spaces in the Correlation property name, it caused issue number 2 and 3 (may be 4 also) in this Messages related issues (in qa5) - 3 #1764
   And when I used a apostrophe it caused issue number 9 there.

For the message name we have said that no spaces and special characters are allowed. But for the correlation property name no such message is shown, so I assumed I can use spaces there.

2. And we are not validating the user inputs for the message name/correlation property name/retrieval expression.
   I think we should validate it and if there is an issue which what the user has entered we shouldn't allow to save it.

@theaubmov please correct the spelling in the word message here

And in the 2 places where or is used I think it should be 'nor' instead. But I am not 100% sure about :-)
