Battery Usage, Performance and Stability

- Amethyst appears about 33% battery over 8 hours usage. This looks to be the highest rate of all the apps and faster than the screen at 34% over 13 hours.

- I usually keep the app open so that it doesn't need to reload data. Persisting data longer could help that case.

- As more optimizations are made, battery life should likely improve as well as application stability. It will freeze and stop responding from time to time, prompting a close dialog. The next update at "0.17.4" I think should have some fixes here?

- I've disabled the global feed for all relays and that has helped, atleast for the search/global view, seems to have helped.
