Allow inline shaders

Simply include the `inline` option when specifying a shader to
pull it in from the string, instead of a file path:

``` javascript
glslify({
  fragment: 'void main() { gl_FragColor = vec4(1.0); }',
  vertex: [
    'attribute vec3 aPosition;',
    'void main() { gl_Position = vec4(aPosition, 1.0); }'
  ].join('\n'),
  inline: true
})
```

Alias frag/vert options

Because I like the symmetry :)
Re-expose glsl transform streams from browserify.

Pass in an array of glslify transform streams like so:

``` javascript
glslify({
  vert: './shader.vert',
  frag: './shader.frag',
  transform: [
    'glslify-hex'
  ]
})
```

And they'll be applied to the shader at build time.
