[meta] style guideline adherence

[dante]

There are a lot of flubs in our own commitment to style guidelines. This meta ticket is to be used to commit small style guidelines changes. This is mostly for small nits, like spaces between if () and } else { etc.

the guidelines are defined at: http://dojotoolkit.org/developer/StyleGuide

In [15808] this line of _base/html.js:

af(node, 1).Enabled = (opacity == 1 ? false : true);

is replaced with this one:

af(node, 1).Enabled = !(opacity == 1);

Why not like this:

af(node, 1).Enabled = opacity != 1;

saving 3 characters and making it easier to understand.
