comparison mde/gui/content/Content.d @ 91:4d5d53e4f881

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Shared alignment for dynamic content lists - finally implemented! Lots of smaller changes too. Some debugging improvements. When multiple .mtt files are read for merging, files with invalid headers are ignored and no error is thrown so long as at least one file os valid.
