GoGreen Mobile has render issues on Opera Mini

Viewing the GoGreen Mobile site on Opera Mini displays various rendering issues. Most of them are minor issues.

Big issues:
-Site doesn't scale in width correctly. Grey space on the right, next to the content, is displayed. Because opera mini doesn't support the meta viewport tags, there's no quick fix for this. Only custom CSS for Opera Mini would fix this, but this is time-consuming and a bad solution. Since it will involve setting widths and heights to fit the full screen (minimal resolution of 800x480), and thus images have to be upscaled as well, which will look rather ugly. Opera Mini is build to view normal webpages (not optimized for mobile devices) on a mobile device. With this in mind I don't think it's a bad solution to just disable the redirect for Opera Mini, so that the default GoGreen site is displayed. Opera Mini would probably have less problems rendering the main site, but this has to be tested thoroughly however.

Minor issues:
-Search remove button not positioned correctly
-Sort by filter height too big, when expanded.
-Second level menu buttons (popular, recent, search) are not aligned with first level menu buttons.
-Main nav has some gray space below it.
-Change language: language text not vertically aligned properly.
