CHANGED: Settings are now stored in versioned sub-directories
ADDED: First-run dialog for migrating settings from a previous version
CHANGED: Settings are now stored as JSON files instead of wxConfig-style INI files
CHANGED: Color settings are now all stored in a separate settings file
CHANGED: The symbol editor and footprint editor now have their own settings files
CHANGED: Color settings are no longer exposed through BOARD object
CHANGED: Page layout editor now uses Eeschema's color scheme
Settings are now managed through a central SETTINGS_MANAGER held by PGM_BASE.
Existing settings will be migrated from the wxConfig format on first run of each application.
Per-application settings are now stored in one class for each application.
This refactors the symbol field editor's checkbox state-saving code to
deal with multiple projects with disjoint field sets more consistently.
For instance, imagine I have a two projects
* Proj1 has fields A, B, C
* Proj2 has fields A, B, D
Under the old scheme, when I switch from one project to the other the
state of fields C and D will be forgotten. With the new approach,
however, they are retained.
Not to mention, the implementation is considerably simpler. Fixes
1) Commit in-progress edits before closing preferences.
2) Handle default fields in Symbol Fields Editor.
3) Save state of checkboxes in Symbol Fields Editor.
