de-uglify the UI

[magland]

• More consistent colors (and title bar color should not clash so much with the rest of the UI)
• Proper text alignment on left panel
• Less vertical space in top title bar
• Proper vertical text alignment on editor toolbars

I’d like to add to this that we should probably have the text editors default to light UI, not the current dark style

I am going to do some work on this now. It certainly won't solve everything but I will aim to make an incremental improvement.

I made #167 #168 and #169

Now I will pause from working on this issue.

With all of the above merged, is this issue completed?

I think the remaining item is the consistent color scheme. We can open a separate issue for that.
