The topic editor's hand-rolled markdown treated any single _ or * as
emphasis, inside URLs and #alias:server / @user:server too, and built the
plain topic by stripping tags, so the underscores were lost for every
client. It also left " unescaped in link targets.

buildTopicContent() now uses the composer's inline markdown parser (links,
bare URLs and HTML escaping as for messages) and treats _ between two
letters/digits as literal (CommonMark), except inside code, link targets
and URLs. The plain topic drops the markers but keeps links as
"text (url)" and decodes entities.

Fixes #262
