Eran Tiktin de441916d6 Add a comment to build instructions about cpplint
I added a mention of `cpplint.py` in the build instructions.
The reason, is because it's easy to miss it's existence. Even if you
noticed it's mentioned in `coding-style.md` you might mistakenly think
that `test.py` runs it).

# Build instructions (Mac)
## Prerequisites
* OS X >= 10.8
* [Xcode](https://developer.apple.com/technologies/tools/) >= 5.1
* [node.js](http://nodejs.org) (external).
If you are using the python downloaded by Homebrew, you also need to install
following python modules:
* pyobjc
## Getting the code
```bash
$ git clone https://github.com/atom/electron.git
```
## Bootstrapping
The bootstrap script will download all necessary build dependencies and create
build project files. Notice that we're using `ninja` to build Electron so
there is no Xcode project generated.
```bash
$ cd electron
$ ./script/bootstrap.py -v
```
## Building
Build both `Release` and `Debug` targets:
```bash
$ ./script/build.py
```
You can also only build the `Debug` target:
```bash
$ ./script/build.py -c D
```
After building is done, you can find `Electron.app` under `out/D`.
## 32bit support
Electron can only be built for 64bit target on OS X, and there is no plan to
support 32bit OS X in future.
## Tests
Test your changes confirm to the project coding style using:
```bash
$ ./script/cpplint.py
```
Test functionality using:
```bash
$ ./script/test.py
```
