Display rounded file sizes in web pages

[manymiles]

I'd like to suggest the files sizes displayed on the recordings page be round to the nearest whole integer.

I attempted to make two suggestions with two different commits, but clearly, my understanding of how to do that on github is lacking.

In any event, this now includes the following suggestions:

• round the file sizes to whole numbers on the audio recordings page
• Add some information about the playing audio file to the audio player

Many thanks for your contributions @manymiles - I'll review, merge and test in a couple of days (pretty busy with work at the moment) 👍
