- solved issue #292 where a new geometry renamed with many underscores failed to store the name in a saved project
- the name for the saved projects are updated to the current time and not to the time of the app startup
- some PEP8 changes related to comments starting with only one '#' symbol
- New feature: added the capability to view the source code of the Gerber/Excellon file that was loaded into the app. The file is also stored as an object attribute for later use. THe view option is in the project context menu and in Menu -> Options -> View Source
- modified the initial size of the canvas on startup
- modified the build file (make_win.py) to solve the issue with suddenly not accepting the version as Beta
- fixed a bug where in Excellon editor when editing a file, a tool was automatically added. That is supposed to happen only for empty newly created Excellon Objects.
