Simplify the way to use the character name in a string

[theludovyc]

Curently you sould do "Hello, my name is <gd.name>!"

I propose "Hello, my name is <gd>!"

When we use only the tag, it return the name by default.

Because, we need to access the name a lot in a dialog script.

I see this is a good idea @theludovyc, but remember to make sure that for examplegd.age still works after this change.
