use gzip middleware

[eternal-flame-AD]

Currently, the built js bundle for WebUI is nearly 1 megabyte, which takes quite significant of time to transfer on a unstable network. With the plugin functionality the size nearly doubled (~1.8MB) due to the packed code editor and extra logos. Using gzip can significantly decrease the size transferred (60%+ bandwidth saved).

Could you update this pr, it now has merge conflicts after merging #110 .

[eternal-flame-AD]

Okay, I have ran go mod tidy against the merge and the confliction should be resolved.

@eternal-flame-AD I'm planning on adding a text chat for the Gotify project, which platform would you prefer? gitter, Slack, Discord or something else? (I'm asking you because I think you would probably use it) (I'd probably prefer Discord but I don't really care.)

[eternal-flame-AD]

I would prefer slack, I am a little more active on slack than Discord:), but Discord would be great too because a lot of project uses that.
