Improve zoom scale

[Zverik]

Fixes #1943. Zoom scale was not generated programmatically, instead I chose each value by hand, so that the scale bar is immediately readable and tends to show round values.

@ferdnyc @N3WWN - Opinions on this? I'm not fussy about zoom levels, so I don't have much to say on the matter. I guess I do prefer the shorter code in this PR, that's all I can say. 😆

@DylanC - Do we have all branches building AppImages at this point? Or is it just the develop and master branches?

I ask because, if it's all branches, would it make sense to put this into a new branch so we can play with these values without altering the current ones?

I will say that I do not like the current zoom values, so it's more than likely that I'll prefer these. 😜

@N3WWN - I think its just the develop and master branches. Btw, its easy to try if you just paste the line of code over the previous. I gave it a shot just now.

I don't have much more feedback but it did feel better... if that's even considered an endorsement for it. The increments just seemed a little bit more natural and not so severe.

I was trying to figure out how to do this... I'm using the AppImage so have to try to intercept the reading of the file between hitting Enter to execute the AppImage and when OpenShot actually launches. The /tmp/.mount_* directory that the AppImage creates is read-only, so that's causing issues, too.

Having only spent about 15 minutes on this yesterday, that's where I'm stuck at.

@N3WWN - Oh sorry, I mean't to say in the source code. I have it building on my machine locally. So I put this change in and gave it a whirl. Maybe @ferdnyc can try it when he has the chance. His feedback is usually quite massive and detailed. (almost the size of a little novel) 😆

This looks great! I just gave it a try and it works nicely! Merged.
