Add argument parser

[DavidWittman]

Right now apdebug is mostly playing by my rules. Adding an argument parser will provide the ability to manipulate some of the basic options such as:

• strace output file
• max string size for strace system calls
• Addition of headers to the request
• Some other cool things which I can't really think of right now

• Show line numbers of problem calls
• Interface to which the request should be sent
