add 'const' & 'init' variable block

[SebCanet]

Hello, after create a new variable, for example 'toto', we need:

• initialisation: see not only 'int toto' in variable section, but possibility to have 'int toto = 4'
• constant: initialize a vairable and made it, so code in variable section would be 'const int toto = 4'

I tried but I do not know so well what you created to add automatic typing.

Thanks a lot.
