Subject: Make dwmblocks modules async (#1296)

* Make dwmblocks modules async

* Allow dwmblocks signal numbers to be changed

* Become synchronous on manual run and make dwmblocks signal code optional

* Merge latest commits and add retries

* Re-add fail-early to sb-price

* Make the retry logic better + other changes

* Only redirect non-empty output: for when services are down

* Also change modification time

* Robustness not needed anymore because of curl's --output, no more empty files

* Use actual locks instead of pgrep

* Change to more suitable lock file location for user programs

* Implement thetubster's changes (fast retry and bug fixes)
