launcher: Limit copies of massive debug logs in markdown file

Browse source 
When debugging is activated, we could end up with log files ranging in the
multi-megabyte or even gigabyte range. Copying those is expensive from a cpu/io
point of view in addition to clobbering the storage.

Instead of always copying those files, check if they are smaller than 500kB. If
not, don't copy them and instead provide a link to their location.

Fixes #52
