Update our internal copy of Pyflakes for Python 3

Update Issue 1567
Status: Fixed

- Use the latest version available at the moment (i.e. 0.7.3).
Main Window: Reorganize Help menu

- Rename it "Help" instead of "?" (which makes it easier to point to while
talking about it).
- Remove almost all icons associated with its actions (which was making it look
too cluttered).
Main Window: Show Qt Linguist and Designer actions only for WinPython and PythonXY

- I think most scientists don't need quick access to those actions, and those
who do probably won't look for them in Spyder menus.
- Leave them for Pierre's distributions because I guess he still uses them.
Main Window: Don't show "External Tools" in Tools menu if none is active.
Main Window: Remove icons for a couple of actions in the Tools menu

- This makes feel the menu a little bit lighter on the eye.
Merge: Reorganize "Interpreters" menu (now called "Consoles")
Consoles Menu: Remove icon of "Connect to an existing kernel" action

- It had the same icon of "Open an IPython console", which made things confuse.
- Also reword its tooltip.
Help menu: Move IPython help submenu here from IPython Console options menu

- This will give much more visibility to this submenu
Help menu: Show IPython help entries in the Object Inspector when it isn't focused
