* add google+ * sort signin oauth2 providers based on the name so order is always the same * update auth tip for google+ * add gitlab provider * add bitbucket provider (and some go fmt) * add twitter provider * add facebook provider * add dropbox provider * add openid connect provider incl. new format of tips section in "Add New Source" * lower the amount of disk storage for each session to prevent issues while building cross platform (and disk overflow) * imports according to goimport and code style * make it possible to set custom urls to gitlab and github provider (only these could have a different host) * split up oauth2 into multiple files * small typo in comment * fix indention * fix indentation * fix new line before external import * fix layout of signin part * update "broken" dependency
