Switching themes from custom.html

The communication mostly works now and I've added some better error handling in my code.

In gadgetbridge it shows an error whenever I read from or write to the bangle. Chrome doesn't show any errors. Both still have communication issues sometimes when using my interface.

The error gadgetbridge shows is "Malformed JSON from Bangle.js: No value for t". The logs show my shadowclk.json data being fragmented. Do I just need to send it a "t" value first so it doesn't throw that error?
