TxtView 0.0.4

TxtView is a script that shows the text files from the same directory of the song. TxtView script is mostly used to check the information contained in an album directory.
When starting the script, you can right click on a song in your playlist and go to "TxtView -> Open".
Enhancements:
- Option Wrap/No Wrap and Fixed/non fixed chars in the menu
- Using the built-in functions from Python unlike the QDir/file/etc...
- Open With ... in /usr/bin by default
- Use of mimetypes + filename to guess whatever it is a text file or not (I tried magic, but my first note was that it created a new dependence and second.. it didnt do well the job, my default /etc/magic file was empty, at the opposite mimetypes is builtin and does a good job)
