Correct "bottom of the screen" example

[pyfisch]

Due to the line break emitted by the print statement the text doesn't appear at the bottom of the screen but one line above. Using end='' ensures the text appears at the bottom of the terminal window.

This took me a rather long time to figure out. 😆

Thanks, I think we should also update some docs at https://blessed.readthedocs.io/en/latest/location.html and spell out in the first paragraph, the usual need for end='' for print function, and from __future__ import print_function for python 2.
