Use common CoffeeScript function patterns

Currently, a lot of the code base uses excessive parenthesis. By design CoffeeScript does not require parenthesis when invoking a function, unless the function takes no arguments, or some post-fix operators are used. Additionally, function signatures should conform with following pattern:

```
foo = (data, done) ->
#do something
```

Where `data` could be any number of parameters and `done` is the top-level callback.

For example the code [here](https://github.com/ericadamski/collaborative-edit/blob/develop/lib/Client/client_remote.coffee#L155) can be simplified:

This:

```
synchId = setInterval(
(-> remote.synchronize(shareJsDocContext)),
NO_OP_TIMEOUT
)
```

Becomes this with the `(data, done)` pattern and reduced parenthesis:

```
synchId = setInterval NO_OP_TIMEOUT, -> remote.synchronize shareJsDocContext
```
