- when using the Find function in the TextEditor and the result reach the bottom of the document, the next find will be the first in the document (before it defaulted to the beginning of the document)
- 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
- fixed FlatCAMGerber.merge() to merge the self.apertures[ap]['solid_geometry'] too
- started to work on a new feature that allow adding a ToolChange GCode macro - GUI added both in CNCJob Selected tab and in CNCJob Preferences
- added a limited 'sort-of' Gerber Editor: it allows buffering and scaling of apertures
- removed "added ability to regenerate objects (it's actually deletion followed by recreation)" because of the way Python pass parameters to functions by reference instead of copy
- finished the UI, created the postprocessor file template
- finished the multi-tool solder paste dispensing: it will start using the biggest nozzle, fill the pads it can, and then go to the next smaller nozzle until there are no pads without solder.
- fixed bug in Marlin postprocessor for the Excellon files; the header and toolchange event always used the parenthesis witch is not compatible with GCode for Marlin
- fixed a issue with a move to Z_move before any toolchange
- created a prototype postprocessor file for usage with tool probing in MACH3
- added the default values for Tool Film and Tool Panelize to the Edit -> Preferences
- more fixes in camlib.CNCJob regarding usage of toolchange (in case it is None)
- fixed postprocessor files to work with toolchange_xy parameter value = None (no values in Edit - Preferences fields)
- in case that the Toolchange X,Y parameter in Selected (or in Preferences) are deleted then the app will still do the job using the current coordinates for toolchange
- fixed an issue in camlib.CNCJob where tha variable self.toolchange_xy was used for 2 different purposes which created loss of information.
- the units mentioned in HPGL format are only METRIC therefore if FlatCAM units are in INCH they will be transform to METRIC
- the minimum unit in HPGL is 0.025mm therefore the coordinates are rounded to a multiple of 0.025mm
- the version date in GCode header is now the one set in FlatCAMApp.App.version_date
- fixed bug in postprocessor files: number of drills is now calculated only for the Excellon objects in toolchange function (only Excellon objects have drills)
