Added a script to remove the comments from annotated.c

[ghost]

This was mentioned in the readme (although it was followed by "but nah") and I suppose it may be useful.

What is purpose of this?There is already a file without comments.

@farooqkz if you read the annotated.c it has a comment (beginning at line 13) saying this:

• ahh, but now i have to make every code change twice!
• oh well. i could always use some sort of script to process the comments out
• of this and write it to tinywm.c ... nah

the purpose of this pull request is to do exactly what the comment was talking about which is basically for when/if mackstann ever rewrite or change the annotated.c they don't need to do it twice (1st in annotated.c and 2nd in tinywm.c)
