make badge configuration order in-depended

[philippb]

Right now the badge looks different depending on when it's configured.

The configuration is only valid when applied after the badge count is set. The order should not matter.

        self.settingsBtn.badgeValue = "\(count)"

        let x = self.settingsBtn.badgeOriginX
        let y = self.settingsBtn.badgeOriginY

        self.settingsBtn.badgeOriginX = x - 10
        self.settingsBtn.badgeOriginY = y + 3
        self.settingsBtn.badgeFont = UIFont.systemFontOfSize(10)
        self.settingsBtn.badgePadding = 4

is not the same as

        let x = self.settingsBtn.badgeOriginX
        let y = self.settingsBtn.badgeOriginY

        self.settingsBtn.badgeOriginX = x - 10
        self.settingsBtn.badgeOriginY = y + 3
        self.settingsBtn.badgeFont = UIFont.systemFontOfSize(10)
        self.settingsBtn.badgePadding = 4

        self.settingsBtn.badgeValue = "\(count)"
