pep8 loose compliance about xpra HOT 2 CLOSED

Better now:

find xpra/* -maxdepth 0 -type d -exec echo -n "{}    " \; -exec bash -c "pflake8 {} | wc -l" \; | grep -ve ' 0$'
xpra/client    2173
xpra/net    1237
xpra/platform    3200
xpra/scripts    1020
xpra/server    2594

from xpra.

Good enough for now, down to zero warnings with the config we ship, which ignores only a few modules / warnings:

Nothing major here:

• examples and platform modules (macos and win32)
• E203 whitespace before ':': 5504 hits
• E221 multiple spaces before operator: 351
• E231 missing whitespace after..: 2862
• E252 missing whitespace around parameter equals: 628
• E262 inline comment should start with '# ': 224
• E265 block comment should start with '# ' : 1653
• E741 ambiguous variable name..: 145
