GUI has inconsistent capitalization

Several of the developers are not native English speakers, and these buttons have been added or edited by various people at various times. While they probably intended them to be written exactly as they are at the time they wrote them, there's certainly some precedent for them considering and fixing these issues on the tracker. See MC-32250, MC-34642, MC-2453, MCL-2176, and finally MC-56254, which I have resolved as a duplicate of this report because it more clearly demonstrates the issue.

For what it's worth, I personally am not advocating for any particular style, just that the style is consistent. There isn't really a clear rule in English for capitalization in cases like these, so confusion is understandable. It's just one of those silly things that, as a graphic designer, really gets under my skin.

Also, I didn't want to make the picture a mile tall so I only showed a few examples that I remembered offhand- there are probably other cases scattered around (I think there's a block or item name with this problem somewhere).

One thing you didn't list: the statistics. All of them have all words capitalized, except for (including the 1.8.2-pre1 ones):

• Games quit

• Noteblocks played

• Noteblocks tuned

• Plants potted

The statistics can't be translated (see [MC-46341] and [MC-77880]). And while checking for non-translatable strings, I found out that the spectator commands (that also can't be translated) also have some inconsistencies, like "Close menu" and "Next Page". There are some more I found but always forget to point here, so I'll do that when I remember to.
