Provide ETA on Grimoire spell casting (Issue #136)

[connorjclark]

Hovering over a spell that can't be afforded yet will display an ETA for when it can be afforded.

If a spell can be afforded, "Recovery in" relays how long until you will be back to the same mana, if you cast the spell now.

If a spell can be afforded once, but not twice, "Afford again in" relays how long until you can cast the spell again, if you were to cast it first now.

Okay, finally looking at this (sorry for the delay!) First thing I noticed is that you use the average magic per second for a second. Looking at the code, the real amount changes every single frame in a second, which means there are actually 30 different magic per second per second. Why did you opt to go this way?

I also noticed, you removed the onmouseover backup data I saved for both buildings and upgrades. What was the reason? I guess you saw no usage of the backup data, which is true, I guess, but I wanted to backup anything I modified in the original code.

A few more things.

My whole addon uses DOM to change things, I rather not start using string appending, like the original game does, now. (Edit: Apparently I do add none DOM stuff sometimes, my bad. I do know I tried to avoid it as much as possible though).

I already have a format time function. I don't think it was needed to remake another one.

Sorry if this is harsh criticism. I am really grateful for your help, as I still don't understand your commented math formula at all (lol), but I think I won't be using much of your code. =(. Thanks again for getting a jump start and making it easier for me to figure out how to implement it.

Sorry, I only used this as reference. Thanks again! This feature has been added to Version 2.0042.2. I ended up not adding the "afford again" stat.
