Plugin validation: More than one top-level folder "allowed"

[s-m-e]

If I understand the idea correctly, a plugin ZIP-file should have exactly one plugin top-level folder. Not more than one. If my understanding is correct, there is an issue in the validation: It only checks the "first" top level folder and does not care if there is more than one. (The current plugin installer in QGIS on the other hand also does not check if there is more than one sub-folder and just unpacks everything.)

    namelist = zip.namelist()
    try:
        package_name = namelist[0][:namelist[0].index('/')] # PROBLEMATIC SECTION
    except:
        raise ValidationError( _("Cannot find a folder inside the compressed package: this does not seems a valid plugin") )

    if package_name.endswith('/'):
        package_name = package_name[:-1]
    initname = package_name + '/__init__.py'
    metadataname = package_name + '/metadata.txt'

Dear @s-m-e

It only checks the "first" top level folder and does not care if there is more than one

That's right, I suggest handling this with a non-blocking warning for now. Please find the proposed PR at #349
