Adds a new set of 'New Project' dialogs to allow authors to easily copy
keyboards from local filesystem, Keyman Cloud (including a keyboard
search web page, implemented in keymanapp/keyman.com#536), and
directly from a GitHub URL. Adds related documentation.
Fixes: #13073
Depends-on: keymanapp/keyman.com#536
Fixes#10135.
Adds a new LDML Keyboard Project template and form, and allows
instantiation from kmconvert command-line and from the New Project
dialog in Keyman Developer IDE.
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
