Do not interpret HTML tags in changeset messages
Do not interpret HTML tags in changeset messages

When displaying changesets, the commit message is now manually
transformed (adding href, bug and bugnote links + nl2br) instead of
calling string_display_links(), which avoids unwanted html tags
processing by the MantisCoreFormatting plugin.  Rationale: commit
messages being plain text, any html they may contain should not be
considered as formatting and must be displayed as-is.

Fixes #93
