pcb-rnd 2.1.2
~~~~~~~~~~~~~

This release of pcb-rnd focuses on code cleanup and fixin bugs. The three
major cleanups are the full netlist code rewrite, introduction of
CAM jobs which will long term replace the more limited gerber name
styles, and refactoring the KiCad file read code for more proper operation.

Feature highlight:

1. CAM jobs from the command line with -x and from the GUI with the
   cam export dialog using {f c}

2. live scripting: dialog box with a script editor for real time
   development and experimentation with scripting

3. almost complete KiCad load support for files generated with version 4
   or older

4. optional gerber drill files

5. option to directly export in the excellon format, without any gerber

6. full netlist code rewrite: support for network mapping, renaming, merging

7. actions and GUI for starting a board without a netlist and build
   the netlist from within pcb-rnd

8. new netlist dialog with enhanced functionality (same code for all HIDs)

9. new log window with enhanced functionality (same code for all HIDs);
   log is persistent (messages before GUI startup are not lost);
   export log to file button/action
