Visually disabled zoom control buttons showing wrong state for basemaps with different max zoom levels

[seyfro]

With v0.5 the following feature was introduced:

• Improved zoom control buttons to become visually disabled when min/max zoom is reached

This works fine when multiple basemaps are used which all have the same max zoom level. I found one small issue - following scenario:
Basemap A, max-level 18
Basemap B, max-level 17
->User selected basemap A and zooms to level 18, then switches to basemap B.
Result: zoom level decreases back to 17 (new with 0.5 which is great BTW ;-), but zoom control button is still visually disabled, although + can be clicked one more time.

Thanks, will take a look some time. Pretty minor issue though.
