When saving an email, its contents pass through convert_inline to ensure wide e-mail client compatibility. One phase of that process is the conversion of classes to inline styles, which involves parsing through all the styles in all the stylesheets of the document, and matching them with each element in the DOM. That is an extremely expensive process and because of that, saving an e-mail can take a very long time depending on how large the DOM is. This refactors it for performance gains. Tested on an exaggeratingly big DOM, what used to take about 12s now takes about 5s. - The process of parsing through the document's stylesheets is now done on opening the email (about 500ms) rather than on saving it so we split the processing time between the two. - When parsing the stylesheets, we now also preprocess them by grouping whatever can be grouped together and precomputing the specificity so as to sort them appropriately. This has the benefit of considerably reducing the number of rules to iterate over for each element (from 11k+ to 3k+). - In the process, some things were re-written for improved readability.
