We still want these till we officially drop the EOL Node versions

In this way his past contributions are mapped correctly, including collapsing
two different ways of writing "ę" into one.

## Supported Environments

| OS | Architecture | Node |
| --- | --- | --- |

| OSX | x64 | 0.10, 0.12, 1, 2, 3, 4, 5, 6, 7, 8, 9 |

| FreeBSD 10+ | amd64 | 4, 6, 8 |

*Linux support refers to Ubuntu, Debian, and CentOS 5

* gaze.watched returns an object

Since it returns an object, we need to run through the keys, a simple index of isn't enough.  This should fix https://github.com/sass/node-sass/issues/2139

Pointing them to the release notes is safer since it will accurately reflect the support for that version of node-sass

Removed 55 since it was part of a prerelease Node 8 only

Nan::ObjectWrap Docs: https://github.com/nodejs/nan/blob/master/doc/object_wrappers.md#api_nan_object_wrap

Prior to this, all wrapper Objects would never be deleted, allowing memory to grow unbounded.

Example:
The following, would leak WrapperObjects, and never

```
while (true) {
  new sass.types.String(‘I LEAK’);
}
```

* boolean
* function-bridge
* map
* string

Improved the grammar and clarity of the instructions in this project's README

* Remove Node 0.10 and 0.12 from travis config

These will always fails now due to https://github.com/sass/node-sass/issues/2100. We manually verify support when building release binaries so there's no value in failing CI. It's scary to contributors.

* Remove Node 0.10 and 0.12 from appveyor config

These will always fails now due to https://github.com/sass/node-sass/issues/2100. We manually verify support when building release binaries so there's no value in failing CI. It's scary to contributors.

* Link to the troubleshoot guide for Node < 4 installation issues

Help people search for keywords because noone reads the help guides anyway.

Fix a couple of typos and minor Markdown tweaks.
