jp (blog, common): moved and improved edit code from blog: - a new "common" module is there for code commonly used in commands - moved code for editing item with $EDITOR there - moved code to identify item to edit there - aforementioned fontions have been made generic - a class BaseEdit is now available to implement edition - HTTPS links are handled (only HTTP links were working before) - item can be use if all previous methods fail (url, keyword, file path).
