Comply with PEP8

[0xjac]

The code has multiple PEP8 violations to be fixed, including but not limited to:

• two blank lines before a class declaration (L12, L17, L25, L31, L35)

• class name should use CamelCase (L12, L17, L25, L31, L35)

• use new style classes: class ClassName(object): (L35)

• 2 spaces before comment: # (L44 and more)

• block comment should start with a pound and a space after it (L48, L91, L199, L204, L315)

• missing space after , (L98, L220, L230 and more)

• redundant parenthesis (L220, L224, L227, L230)

• missing spaces around operators: 3*x -> 3 * x, self.actions+="y" -> self.actions += 'y'

I'm also leaving here a couple other minor issues which are not exactly PEP8:

• use .format instead of % for string formatting.

• cannot return value from init (L52, L66, L72, L95, L101)

  If you need a catastrophic failure here, raise an exception, preferably a custom one for clarity.

• use setup_req.UnitType in {0x06, 0x07} instead of or L90

  Using set membership will make your condition shorter and more readable, esp. if you need to add another value
  later on.

• In my opinion I would remove the t1 variable or if you want to keep it, use a clearer name such as loop_thread (L102)

• variable ACTION_SIZE should be lowercase. (L116)

  This is irrelevant once #3 is fixed
