Refactoring the timeout retries into a more general 'retry policy' with
support for retrying on HTTP 429 (Too Many Requests) and other responses
with a `Retry-After` header
The delay between requests is controlled by a combination of a 'backoff'
(currently only a simple linear backoff), and honouring the
`Retry-After` value (longest delay wins)
This makes the 'rate limiter' an optional argument as well, removing the
use of `nil` when one isn't supplied

* Adds additional comments to help explain the situation
* Fixes bug that could unlock mutex too early
* Fixes LIES where Gemini gets a nonce and then proceeds to declare it doesn't get a nonce causing an unrecoverable lock
* Fun new concept! The creation of a tested timed mutex. Unlocking an unlocked mutex cannot occur and response can be checked to verify whether the mutex was unlocked from timeout or command.
* Adds new cmd parameter "dispatchjobbuffer"
* Expands comments and renames benchmark. Makes `Timer` property private
* Happy little linters
* Renames jobBuffer and all related instances to jobs limit
* Tiny error message update
* Grammatical fix and setting dispatch.Start to use defaults

* Adds btcmarksets websocket :glitch_crab: fixes alphapoint features
* Adds extra data not in the documentation :/
* Replaces websocket features by using protocol features. However, it breaks it due to import cycles. I'm not sure what I'll do just yet
* Removes import cycle via duplicate structs.
* Increases coverage of config with `TestCheckCurrencyConfigValues`. Moves all currency pair package types into their own files or places it at the bottom of files if necessary
* Increase coverage in code.go
* One way of determining a test has failed, is when to it fails. Removed redundant explanation
* Increases code coverage of conversion

Adds new order cancellation struct type. Updates old tests that pointed to the wrong unrenamed methods
* Sets up tests for all supported exchanges. request.DoRequest errors when response status is not 200
* Updates alphapoint, coinut, hitbtc, lakebtc cancel order implementations. Finishes testing
* Adds localbitcoin cancel order wrapper support
* Fixes tests and build issues. Adds WexIssue flag for tests

- Modifications made to the request package. Planned improvements will be
sending requests on intervals, rate limiter back off support, dynamic tuning
and requests packaged into a request job group.
- Can modify each exchanges individual HTTP client (e.g timeout and
transport settings).
- Bot now uses an exchange config HTTP timeout value.
- Bot now uses a global HTTP timeout (configurable).
- Batched ticker request support for exchanges.
- Ticker and Orderbook fetching now are spanned accross multiple
go routines and regulated by a sync wait group.
- Fixes hack used to load exchanges, now uses a sync wait group.
- Ticker and Orderbook storage and fetching now uses mutex locks.
- New pair function for finding different pairs between two supplied
pair arrays. This is used for currency pair updates for exchange which
support dynamic updating.
- Shows removal/additions of dynamic updates currencies.
