Legend Strings Cleanup

[Navid200]

I am suggesting some changes by removing some words that seem redundant to me.
Please let me know if you think this is not clear in English.

Before	After

The word color is currently used on this page.
My problem with that concept is that we are talking about the legend page. Color is what a legend is about. There is nothing other than color.

Of course, we can some day give options to the user to change the dot to look like a plus sign or a circle or a star ...
Then, legend would be about color as well as marker shape.
But, we don't have that option now in xDrip. Stating color so many times on this page seems redundant to me. So, I have removed the word color in an instance in this PR.

When a heading says background, I expect everything in that section to be about background, and it is.
So, there should be no need to state background for every item in that section. So, I have removed those.

The word Glucose is used on this page. xDrip is mainly about glucose.
We do show heartbeat. I appreciate that. But, that is what needs clarification, not glucose. I would state heartbeat for a dot or text that is not glucose. But, I wouldn't include glucose for a dot or text that is about glucose because that is almost everything.
I have removed glucose from a few instances.

I think this is probably okay but it will trigger a lot of new translations

[Navid200]

Would it become acceptable if I break this into 2 PRs and you can merge them in sequence instead of in one shot?
Or, would it be acceptable if I break it into 3 PRs?
Or, what do you suggest please?

[jamorham]

Its not the size of the PR it is the work we are asking others to do so we have to be sure we're not going to change our minds and alter it all again shortly afterwards.

Now, I understand and agree.

Just to let you know, we have a developer working on this: #3565
What you see in that discussion is all I know about the status.

After I had that conversation, I realized that sooner or later, we may have one more item added to that menu. I have to say that menu looks too crowded to me. That was when I decided to clean it up.

We can forget about this PR for now and wait for that work to complete. When/if that work is done, we can then decide how to deal with the menu including the new item.

I agree 100%; creating unnecessary work for volunteers is unacceptable.

Regardless, I am going to look at this PR now very carefully and review everything several times. I will also imagine that the new item has been added when I do the review and see if we need to make any changes to avoid any more changes needed later.
