recent unity versions, editor logs have moved into project folder:

Logs moved to project-relative Editor.log file, and subsequent logs will only be written to this file.
F:/Unity/projs/myproj/Logs/Editor.log

TODO

• check which version the move happened *6.5 and later https://docs.unity3d.com/6000.5/Documentation/Manual/log-files.html
• add context menu for opening editor.log in recent projects list
• add shortcut key to open editor.log from selected project (ctrl+L)
• handle build report fetching from that log file (maybe it reads editor.log and gets folder name from there? but if have 2 editors open, then it fails.. probably need to add in project context menu)
• tools/editor.log button could still open editor log for currently open unity editor (if 6.5 or later), if one editor running
