New and improved patch! Now with more compatibility!

New in v0.1.3:

• Detects Python 2.6–2.7 and instructs the user to use Python 3.x, instead of crashing with a generic error message;
• Platform-specific instructions (e.g. when the script is run with the --help flag or an invalid syntax);
• Added an optional -s flag to play an alert sound when the script is done;
• Improved code clarity (fixed indentation);
• Added OS X and Windows binaries which do not require Python 3 to be installed, but there is no guarantee they will work.

New in v0.1.2:

• Pillow is automatically installed if needed, using the command pip3 install Pillow.

New in v0.1.1:

• Commented the code extensively;
• Handled some exceptions;
• Reduced line width to 80 so the code is somewhat readable;
• Added the -I flag to choose an interpolation method when rotating (used to default to bicubic, now offers a choice between nearest neighbour, bilinear and bicubic);
• Tried to follow Python style conventions to the extent of my knowledge (which isn't saying much).
