Rename the "PEG" variable to "peg"

Browse Source 
So far, PEG.js was exported in a "PEG" global variable when no module
loader was detected. The same variable name was also conventionally used
when requiring it in Node.js or otherwise referring to it. This was
reflected in various places in the code, documentation, examples, etc.

This commit changes the variable name to "peg" and fixes all relevant
occurrences. The main reason for the change is that in Node.js, modules
are generally referred to by lower-case variable names, so "PEG" was
sticking out when used in Node.js projects.

### JavaScript API
In Node.js, require the PEG.js parser generator module:
var PEG = require("pegjs");
var peg = require("pegjs");
In browser, include the PEG.js library in your web page or application using the
`<script>` tag. If PEG.js detects an AMD loader, it will define itself as a
module, otherwise the API will be available in the `PEG` global object.

The method will return generated parser object or its source code as a string
