Add `aria-label` attribute to graphical buttons

[ndarilek]

Hey,

I'm a blind TiddlyWiki user trying to use this plugin in a few projects. TiddlyWiki is by and large accessible, and by extension so is Projectify, but there are some buttons that are essentially just span tags with no associated text, rather than button elements with their associated a11y benefits.

Ideally these could all be <button/> but if they can't be, could you please add aria-label="..." or alt text to these images buttons? I'm poking around in the source to try doing it myself, but there's a bit of a chicken and egg in that I can't figure out what some of these do just from context, or from clicking on them in the demo.

Thanks.

Hi @ndarilek, thanks for the suggestion, I will make sure Projectify is more accessible.
