comparison mde/gui/widget/miscContent.d @ 115:1b1e2297e2fc

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Enums handled more generically now via either a popup list or flat list of BoolContentWidgets. EnumContent is an IContentList with BoolContent sub-contents. Content modules moved around (again). ContentListWidget can now list horizontally. Log-level setting callback.
