use log viewer stack trace summary for threads view

[zspitzer]

Some nice feedback from @DominicWatson

the full java stack traces are quite verbose in the threads view, would be nice to just show the cfml stack as a summary

i.e. here

this is how the https://github.com/zspitzer/lucee-logviewer shows a summary

vs

https://github.com/zspitzer/lucee-logviewer/blob/refactoring/source/cfml/plugins/LogParser.cfc#L266
