Show text size and text color in menu bar

[monasobh]

As a presentation creator, I want to be able to see the text size and text color of my selected text all the time in the menu bar. It would help me to layout my slides faster. E.g if I want to change another text to the same size as the selected one, I can just see it in the menu bar next to the "text size" button.

• small button next to the exsisting "Text size" button to show text size of selected text all the time
• button shows actual size and color
• if you select a text with two different text sizes, the button should not show any text size (same for text color button)
