Add connection timeout + misc improvements

[austin-bowen]

Primary Changes

• Add optional connection timeout, e.g. gTTS("text", timeout=1.2).
  • timeout defaults to None, so default behavior is unchanged.

Misc Improvements

• Fix bug in _tokenize() where empty tokens were still allowed through.
• Replace _len() function with just len(); it is not needed, as Python 2 is no longer supported.
• Fix typos.

Wow I had a lot of typos!
Thanks a lot for this, and for the cleanup (there's many Py2 recents indeed).

I'll only be able to review more thoroughly after the weekend (earlier perhaps) but very useful addition thank you!
