Messed up method signature for keyword arguments and *args

[kopischke]

Steps to reproduce:

1. write a method with the following signature:

   def my_method(*args, option: false)
   

2. document it using YARD:

   # @param args [Array] classic vintage args
   # @param kwargs [Boolean] :option (false) a new fangled kwarg
   

3. run yardoc on the file with my_method

4. open the YARD documentation for my_method

Expected result:

- (Object) my_method(*args, option: false)

Actual result:

- (Object) my_method(option: false, *args) 

Notes:

Keyword arguments correctly follow named args, but always precede the *args array.

Should be resolved by #785.

@lsegal I can confirm pointing at master works. Any idea when the next release will be?
