* Eliminate modal annotation warning dialog when generating a netlist fails
due to components that are not annotated.
* Add warning message to annotate dialog.
* Change 'Silent mode' -> 'Always ask for confirmation'. Default on
(Same behavior as before, though arguably, it is very annoying and
should probably be default off)
* 'Automatically close dialog' -> 'Keep this dialog open'. Also changed
the default to _not_ keep the dialog open (what is keeping it open even
useful for ?)
* Add code to test if any of the components in the schematic cache have been changed
in the component libraries.
* Prompt user to accept or reject components when changes are found.
* If the user chooses to use the components in the cache, create a new library with the old
components and add it to the beginning of the component library list so the schematic will
not be changed.
* Create dialogs to handle user feedback and status.
File "rules" has instructional text as comments near top.
2) Convert all text files in repo to LF line ending form.
Any checkout done with "rules" in play will convert the working
tree to native line ending, while keeping repo as LF line ending.
Eeschema: cleaning code. Start work to enhance annotation algorithm.
Already added an option to annotate using sheet number (sheet 1 uses numbers 100 to 199, sheet 2 uses 200 to 299..).
Works fine if deleting existing annotation, but needs work to be used when the existing annotation is kept .
