Readme grammar fix (I need to put this Journalism/English degree to use somehow. )

Hi Chris!  I was taking a look at the tool after it was pointed out by Samuel Lampa on Google Plus (https://plus.google.com/u/0/106548631604770110294), as I think it would be awesome to use when I'm working with C/C++ - I'm a fan of GDB, but sometimes it can be a little frustrating using the CLI. I thought I'd contribute a few grammar fixes/ phrasing changes to the readme (for example, the first sentence is a question, not a statement, so I switched up the grammatical mark). Hope this helps, and thanks for the tool. :)
