Fixes an issue reported in https://github.com/tendermint/tendermint/issues/4595#issuecomment-612667441.
Not sure if this is sufficient to fully remove the reactor, but it fixes the immediate problem.

How to use it:
```
$ . <(tendermint completion)
```
Note that the completion command does not show up in the help screen,
though it comes with its own --help option.
This is a port of the feature provided by cosmos-sdk.
Add Has function, create better handling of errors when adding evidence, usage of error types.

Closes: #4537
Uses SignedHeaderBefore to find header before unverified header and then bisection to verify the header. Only when header is between first and last trusted header height else if before the first trusted header height then regular backwards verification is used.

Previously, many reactors were initialized with the name "Reactor," which made it difficult to log which reactor was doing what. This changes those reactors' names to something more descriptive.
- defined what variables needed to be changed in the `config.toml` in order to run a validator.
- Briefly explained how a sentry node archtecture should look
- add section explaing importance of key secruity

Closes: #4546
The algorithm uses an array to store the headers and validators and populates it at every bisection (which is an unsuccessful verification). When a successful verification finally occurs it updates the new trusted header, trims that header from the cache (the array) and sets the depth pointer back to 0. Instead of retrieving new headers it will use the cached headers, incrementing in depth until it reaches the end of the cache which by then it will start to retrieve new headers from the provider.
Mathematically, this method doesn't properly bisect after the first round but it will always choose a pivot header that is within 1/8th of the upper header's height. I.e. if we are trying to jump 128 headers, the maximum offset from bisection height (64) is 64 + 16(128/8) = 80, therefore a better heuristic would be to obtain the new pivot header height as the middle of these two numbers which would therefore mean to multiply it by 9/16ths instead of 1/2 (sorry this might be a bit more complicated in writing but I can try better explain if someone is interested). Therefore I would also, upon consensus, propose that we change the pivot height to 9/16th's of the previous height
