* set tooltip text in monet_file_chooser_button
* update copyright in window.py and add one in plugin_row.py
* update local.sh and fix 'user' rule in Makefile
* replace all remaining print() to buglog(), and redirect to to_slug_case in utils.py
For now I've moved only buglog and to_slug_case here, but a general purpose of this file is to move any redundant/utility code here as a function, so it can be easily used between other modules.
* replace print() in a codebase with new buglog() function
