Changelog graph: bad rendering past certain number of branching

Issue #608 resolved

Past certain branching level, changelog canvas graph produces bad HTML layout. Code tries to increase its width past 100px, but the rest of HTML layout in the page produces bad results, since both the main graph table and the graph canvas are floated.

See attached image (tested in Chrome & Firefox).

I'll do a pull request to fix this in a moment.
