Servo's code should be beautiful

[brson]

Servo is Rust's showpiece. The maintainability of Servo reflects very strongly on Rust's own design, and its claims about 'programming in the large'.

Additionally, browser engines are notoriously complex and difficult to contribute to for various reasons. Surely many developers could be tempted to contribute to a browser engine with a modern design, and in a potentially much more pleasant language.

When people look at Servo's code they should like what they see and want to participate.

Some general goals:

• Settle on conventions for library naming, binding organization, naming (all kinds), actor and object patterns; document and use them consistently
• Arrange modules consistently
• Identify patterns and abstract them out, into std where applicable
• Order module contents top down so that they can be easily read (I think we mostly do this in servo)
• Document modules

The code should be clean enough that, reading from main, one can easily learn the general structure and behavior of the entire system and the major actors.

Old meta-issue with no real book-keeping, we can probably close this.
