Install PyQt5 from PyPI

[The-Compiler]

Since PyQt5 5.6 it's available as binary wheel including Qt on PyPI.
This will make it easier for contributors too, as they can simply run
tox.

Thanks!

Apparently the pyqt5 binaries are not available for py34. If that's the case, I think it is OK to drop testing py34 with pyqt5.

[The-Compiler]

Alternatively I could use the distribution's PyQt5 for Python 3.4 - what would you prefer?

I'm OK with dropping py34-pyqt5 to simplify things. py34 and py35 are pretty much compatible, plus we are testing py34 with pyside.

To recap:

Windows

• py34-pyqt5 (FAILED)
• py35-pyqt5 (OK)
• py34-pyqt4 (OK)
• py27-pyqt4 (OK)
• py27-pyside (OK)
• py34-pyside (OK)

Linux

• py27-pyqt4 (OK)
• py27-pyside (OK)
• py34-pyside (OK)
• py27-pyside (OK)
• py34-pyqt5 (FAILED)

So I would be OK with dropping py34-pyqt5 in both platforms and add py35-pyqt5 to Travis instead. What do you think?

Sounds good, I hope I adjusted everything correctly! I also adjusted the text in the README.

No longer relevant now that we test with conda 😁
