Increase 1-megabyte file size limit

[rmunn]

The maximum file size allowable in repositories that Chorus handles is 1 megabyte, for reasons discussed here. That commit was made in 2011. Many of those reasons still apply (we don't want to let people shoot their repositories in the foot by adding hour-long video files, for example), but the 1-megabyte limit is becoming too small. Most people have phones with cameras that take 3- or 4-megabyte photos, and if they want to add a photo to their repository, they have to learn how to trim its size and reduce its JPG quality. CPUs and network speeds have also increased, on average, over the past decade, so that larger file sizes, such as 5 or 10 megabytes, probably won't harm repositories all that much now.

So while we still don't want to allow adding video files to Chorus repositories, I believe it's time to consider increasing the file size. A limit of 5 megabytes would allow photos taken by most low- to mid-grade consumer cameras these days, but many high-grade phones are taking photos that are even larger: 6 or 8 megabytes. So I propose increasing the file size limit from 1 megabyte to 10 megabytes. That will allow photos taken by most cameras to be added to a repository. It would also mean that .wav files longer than 5.6 seconds would be possible as well: a .wav file would have to reach 56.69 seconds before its size passed the 10-megabyte limit.

It really is time to do this, and to test it and see how it goes when integrated into LFMerge.
