typo fix [ci skip]

Improve params parser

Better reading flow for the information presented in this guide.
The first part is written in a similar fashion as the "Getting Started
Guide" and can be read from start to finish. The second section
introduces the different testing components that Rails provides and
explains how and when to use them.

The guide is still work in progress.

[skip ci] Fix minor typo

Fixed syslog example in production config template

make disable_with default in submit_tag

Plugins are generated with the version 0.1.0

[Robin Dupret]

The semantic versioning specification uses MAJOR.MINOR.PATCH – it would
make more sense to set the version to 0.1.0 for initial development
since a patch release cannot be created before a minor feature release.

Documentation for ActionView::Helpers::DateHelper :use_hidden option

[Kir Shatrov & Robin Dupret]

* Add missing `def` and remove useless `do` keywords.
* Move `:nodoc:` in front of the methods' definition so that methods
  under these ones are correctly visible on the API.

I would like to change the signature of the Route constructor.  Since
the mapping object has all the data required to construct a Route
object, move the allocation to a factory method.

We should build the routes using the user facing API which is `Mapper`.
This frees up the library internals to change as we see fit. IOW we
shouldn't be testing internals.

we can directly turn it in to a regular expression here, so we don't
need to test its value twice

Oops, I broke the build :(

Fixes the method signature of `assign_parameters` which now takes 6
arguments instead of 4. We likely will end up chaning the method
signature further so good to know this test is here.

This is part of a larger refactoring on controller tests. We needed to
move these methods here so that we could get rid of the `|| key ==
:action || key == :controller` in `assign_parameters`. We know this is
ugly and intend to fix it but for now `generate_extras` needs to be used
in the two methods to access the path and the query_string_keys.

We're adding `:controller` and `:action` to the `query_string_keys`
because we always need a controller and action. If someone passed
`action` or `controller` in in there test they are unambigious - we
know they have to go into the query params.

use `average_scheduled_poll_interval` option instead of deprecated `poll_interval`

Convert Releasing Rails guide to Markdown

Initialize symbols instead of mapping to_sym on the set of strings

this removes the following warning:

```
DEPRECATION: `config.poll_interval = 0.5` will be removed in Sidekiq 4. Please update to `config.average_scheduled_poll_interval = 0.5`.
```

The outer router object already keeps a hash of named routes, so we
should just use that.

Small fixes [ci skip]

refactor the tests with a backwards compatible method call so we can rm
add_route2 from the journey router

then we can let the mapping object derive stuff that the Route object
needs.

now that we aren't doing options manipulations, we can just pass the
mapping object down and read values from it.

since we've extracted the `to` initialization, there's no need for
`process_path`

if `to` was initialized, this method would return, so we can eliminate
the to ||= in the conditional.  Finally, let's return a nil in the else
block so that it's explicit that this method can return nil

Eventually we'll pull this up and delete `process_path`.
