Removing designMode from widget constructor about taurus

[sf-migrator-bot]

I like the idea! I prefer something like the first option.
The weak point is if somebody does this kind of program:

import PyQt4.QtDesigner
import taurus.qt.QtGui

# ...

I propose here what I believe is a safer implementation:

I think we could have in taurus.qt.QtGui an API to check/set if in QtDesigner:

# taurus/qt/QtGui/__init__.py

__designerMode = False

def isDesignerMode():
    global __designerMode
    return __designerMode

def setDesignerMode(yesno):
    global __designerMode
    __designerMode = yesno

When QtDesigner starts, it imports taurus.qt.qtdesigner.tauruspluginplugin.
The taurus.qt.qtdesigner.tauruspluginplugin could set the designer mode to True:

# taurus/qt/qtdesigner/tauruspluginplugin.py

from taurus.qt.QtGui import setDesignerMode

def main()
    setDesignerMode(True)
    # ...

The widgets could check if they are in QtDesigner if needed by doing:

# mywidget.py

from taurus.qt.QtGui import isDesignerMode

class MyWidget(...):

    def __init__(self, parent=None):
        # ...

        designerMode = isDesignerMode()
        if designerMode:
            # ...
        else:
            # ...

        # ...
