This way should be more reliable, because config() is available only after publishing module, however I can't publish module when it does not have config (module.json). In this way I can select all modules from database and generate module.json for each of them.
This commit merges list of all uploaded files and created directories into one page. It also modifies way of uploading files. Special page for uploading files was removed (because of no support for directories) and files can be uploaded only via overview.
Translations was broken because namespace "staticpages" was loaded (registered) after first usage of this namespace. I do not understand this bug, however it should be fixed now.
