Add new `single-key-shortcuts` GSetting, Application.Configuration
property and add UI for it in the Preferences window. When enabled,
load in new `single-key-shortcuts.css` file that has the appropriate
bindings. Update bindings to match Google's current set, and update
shortcut help to match.
Move MainWindow out of the root namespace and add it to Application,
so it can privately share internal state with the Controller. Rename
the source and UI files to match.
Create new Application.AttachmentManager class and move code for saving
attachments there from both Application.Controller and MainWindow since
aside from needing the latter for dialogs it is independent of both.
Create new Components.AttachmentPane widget for diplaying attachents
for an email in the ConversationViewer.
Update ConversationEmail and ConversationMessage to use these two new
classes directly, rather than implementing save management itself or
requiring the MainWindow to wire up signals on these classes.
This default instance was causing double the number of preferred height
events, which was likely creating a race for ConversationWebView. This
might (should?) fix plain text email with quotes sometimes showing up
with a vastly incorrect height.
To ensure that a PageState is constructed properly, make ClientWebView
abstract and use replace the one direct use of the class in the accounts
editor for the signature with a new subclass.
See #283
This moves the individual in-app notification implementation on each of
the editor panes to the editor itself, reducing redundancy and allowing
the editor to issue notifications if needed (spoiler: it will).
This breaks out the problem details dialog out into a seperate class so
it can be used for both problem reports and status problems. Pass in any
service errors to the main window when updating account status, show a
Details button on the service status info bar and show the details
dialog when clicked.
This allows the panes themselves to manage their own headers, command
stacks, and so on. Break out the account list pane out so it's handled in
the same way as the others.
Some remarks:
* Note that Meson adds a hard dependency on Python 3.
* All dependencies and defines are now listed together.
* Some build files were put in their respective subdirectories, e.g. the Geary
engine library will be built from the Meson file in `src/engine`.
* `--fatal-warnings` is no longer an explicit flag, as Meson provides
`-Dwerror=true` for this.
* An explicit resource file needs to be used. The issue to support this from
Meson itself can be found at https://github.com/mesonbuild/meson/issues/706 .
* The `gnome.yelp()` function parses a LINGUAS file so we no longer need to keep
track of all languages in our build system.
* There are no Debian scripts defined in the meson.build files to keep them
clean, but they can be kept as separate scripts in `build-aux`.
* Left out the `dist` target as there is now `ninja dist`
* `geary-docs` is disabled by default, as valadoc-0.38.3 returns errors.
