Indeed I think would be useful to clearly distinguish the GUI from
other functionalities.
And would also fix things like:

{{{# gui/wxpython/core/toolboxes.py:53
def GetSettingsPath():
    # this is for cases during compilation and it is not possible to import wx
    # TODO: if the function would be in the grass Python library there would
    # no need to do this
    try:
        from core.utils import GetSettingsPath as actualGetSettingsPath
        return actualGetSettingsPath()
    except ImportError:
        # expecting that there will be no such path
        # (these files are always check for existence here)
        return ""
}}}

So how to proceed? Should I move this function to grass.script.utils
and then just import the function definition in
gui/wxpython/core/utils.py?

Should I just fix all the following imports in the GRASS source code:

{{{
gui/wxpython/gui_core/gselect.py:69:from core.utils    import
GetSettingsPath, GetValidLayerName, ListSortLower
gui/wxpython/web_services/dialogs.py:35:from core.utils       import
GetSettingsPath, _
gui/wxpython/core/settings.py:29:from core.utils import
GetSettingsPath, PathJoin, rgb2str, _
}}}

What do you think?
