Timo Tijhof 4e64187beb Document and clean up events in all the things
* Document them consistently between secetions Inheritance and
  Static Properties under their own (new) section Events.
* Removed any quotes or brackets around the event name in existing
  @emit annotations
  Search: @emit.*['"{}(){}]
* For every call to this.emit() anywhere, added @emits.
* Fixed all warnings for references to undefined events
  (introduced as a result of the previous point).
  Event handler parameter documented based on the emit() call
  and actual handlers using the event. Usually the latter is
  more elaborate.
* Extend coverage of jQuery as needed
  (copied from mwcore/maintenance/jsduck/external.js
  written by me, hereby implicitly and explicitly released under MIT).

Specifics
* ve.ce.Surface#onContentChange: Fixed type of range from Object to ve.Range.
* ve.ce.SurfaceObserver#poll: Fix syntax for code from {} to `backticks`.
* ve.ui.Toolbar#onContextChange: Doesn't actually emit "clearState" event.
  Removed #onClearState in Tool, ButtonTool and DropdownTool.

# VisualEditor Code Guidelines
We inherit the code structure (about whitespace, naming and comments) conventions
from MediaWiki. See [Manual:Coding conventions/JavaScript#Code structure](https://www.mediawiki.org/wiki/Manual:Coding_conventions/JavaScript#Code_structure) on mediawiki.org.
## Documentation comments
* End sentences in a full stop.
* Continue sentences belonging to an annotation on the next line, indented with an
additional space.
* Types in documentation comments should be separated by a pipe character. Use types
that are listed in the Types section of this document, otherwise use the identifier
(full path from the global scope) of the constructor function (e.g. `{ve.dm.BranchNode}`).
### Generate documentation
#### Gem (Mac OS X)
Ruby ships with OSX but may be outdated. Use [Homebrew](http://mxcl.github.com/homebrew/):
```
$ brew install ruby
```
If you've never used `gem` before, don't forget to add the gem's bin to your `PATH` ([howto](http://stackoverflow.com/a/14138490/319266)).
#### Install
Once you have gem, installing [JSDuck](https://github.com/senchalabs/jsduck) is easy:
```
$ gem install jsduck
```
#### Run
```
$ cd VisualEditor
$ .docs/generate.sh
# open http://localhost/VisualEditor/docs/
```
For more options:
```
$ jsduck --help
```
