Changed relative file to absolute file

Changed relative file to absolute file

Using relative files causes a failure if you open a file within vim that is not in your current working directory. This can lead to unexpected results if there is an file name identical to the one you are editing in the working directory, and no markdown generated if there is no file with that name in the working directory.

Don't remove temporary files, and removed the time delay

Fixed background bug via longer delay and background process. Closes #2
