New commits: commit 731f073f1ff469e446da68c2c75f0ad8ff86c299 Author: Mike Kaganski <mike.kagan...@collabora.com> Date: Mon Mar 6 16:09:54 2017 +0300 tdf#106359: Open Web Query (.iqy) files As per http://support.microsoft.com/kb/157482, the files are plain-text files with an URL and optional GET and POST parameters (static and dynamic). This commit introduces basic support to open these files (without support for POST and dynamic parameters).
