With 4.0-a2, I'm developing a custom style and a custom extension.

• If I remove all the template files from my custom style except for the ones modified, I get a 500 error stating it can't find the html files. It appears to only look in "all" and "prosilver" (my style is named revolution).
• For the extension, if I have template files in the prosilver directory and use my revolution style, my extension doesn't show. The only way to get it to appear is to rename the prosilver directory in my extension to "all".
