Option to rename types about gir-to-d

[dhasenan]

Functions too; jsc_context_throw is mapped to void throw(), which obviously doesn't work.

I think the class directive renames the generated class. There doesn't seem to be an equivalent for functions. While I can use noCode: funcname and manually insert the code, it would be nicer to have gir-to-d handle the rename.

Sincet there's a workaround, this is obviously low priority.

Oh, move takes three arguments: the thing to move, the thing to move it to, and the name to give it in that type.

For renaming functions you can use alias.

alias: throw throw_

alias also works on parameter names.
