Styles are now correctly displayed when 'inline_sources = TRUE'

[Zeioth]

The styles were incorrecly displayed in all sections showing source code when said option was enabled. I fixed it replacing the next line in doxy-boot.js

$( document ).ready(function() { /* code */ });

by

window.setTimeout(function() { /* code */ }));

Also I clarified the readme for an easier installation process. Tested and working.

Ok, ready to merge.

I tested your commits in my projects' docs, and your main – window.setTimeout – is causing a "flicker" when the style is transitioning from – without Bootstrap – to the new visual – with Bootstrap.
Despite this is a valuable contribution, I believe this "flickering" behavior is undesirable, as it is very unconfortable for the final user.

You are right. The fix works perfectly on Firefox, but doesn't work at all in Chrome. I'll look for a better solution.
