RSOD with TW v5.3.5-pre - missing type

@flibbles -- There has been a [Talk thread](https://talk.tiddlywiki.org/t/please-help-final-checks-for-bug-fix-release-v5-3-5/10104/9?u=pmario), where etardiff points out a problem with TiddlyMap. I did find the issue and I think why it happened. The problem is caused at: https://github.com/felixhayashi/TW5-TiddlyMap/blob/2f0a2779c342a3bf1b9e91539296b07b023391d3/src/plugins/felixhayashi/tiddlymap/js/edgeTypeSubscriber/AbstractRefEdgeTypeSubscriber.js#L65 because the type: `tm-body:transclusion` (or similar) is new in TW v5.3.4+ -- It seems TiddlyMap recognises the new "transclusions" and "backtransclusions", but does not know, what to do with it. I think I do have a fix. -- **But** I also needed to fix the gulp tasks because I did get an error message there. too. So do you accept PRs, once I'm sure it actually works?
