For batch builds (e.g. project/compile all) of v2.0 projects, we only
want to build files that are listed in the project's $SOURCEPATH, so
that the project can contain extra folders with source file types that
won't break a project-level build.
Any source file types in extra folders can still be built one-by-one,
which is helpful for investigation and test for keyboard authors, but
will not be built if project build is selected.
This commit also formalizes the source/ SourcePath for upgraded projects
which contain a source/ folder. If the project to be upgraded does not
contain the source/ folder, then no SourcePath is assigned, and any
source file in any folder will be built.
Identifies .xml keyboards when building file list, then shows those
appropriately in the keyboard list. Also enables grouped actions such
as keyboard_compileall for those keyboards.
Relates to #9948. Starts basic support for v2.0 projects.
For all operating modes:
- Remove blank projects / untitled projects mode
- Add Open Project Folder buttons and links
- Remove Project Save As
- Render uses in-memory XML
- Upgrade to v2.0 project file (along with checks)
For v2.0 projects:
- Remove 'Add File to Project'
- Populate Files to list all files in folder (note: consider efficiency
here as currently files are parsed for subfile data)
- Version 2.0 project options and defaults
