This splits the giant EMailRequest to individual EFileRequest, EStockRequest, EHTTPRequest and EMailRequest,
making the first two available globally from e-utils, the othe two are loaded only with mailer,
since no other component uses them.
Add a load_string() method to EWebView. Have EMailDisplay override
load_string() and check that the formatter is not busy before loading
the string. Have EMailReader call e_web_view_load_string() directly
on the EMailDisplay instance, and eliminate update_webview_content().
Add "copy-target-list" and "paste-target-list" to the ESelectable
interface. These are underutilized for the moment, but will eventually
be used to help integrate drag-and-drop support into ESelectable.
Add cut and paste support to EWebView, along with a new "editable"
property and new clipboard signals "copy-clipboard", "cut-clipboard" and
"paste-clipboard".
In EFocusTracker, listen for "owner-changed" signals from the default
clipboard as another trigger to update actions, particularly the Paste
action. (Unfortunately this doesn't work for EWebView since GtkHtml
implements its own clipboard.)
In EMsgComposer, convert GtkhtmlEditor's clipboard methods to empty
stubs, since EFocusTracker will now trigger EWebView's clipboard
actions. Also, intercept EWebView::paste-clipboard signals and improve
the interaction between the HTML editor and the attachment bar based on
use cases in bug #603715.
EFocusTracker tracks the input focus within a window and helps keep
the sensitivity of "selectable" actions in the main menu up-to-date.
Selectable actions include Cut, Copy, Paste, Select All and Delete.
EFocusTracker has built-in support for widgets that implement the
GtkEditable interface such as GtkEntry and GtkTextView. It also
supports custom widgets that implement the ESelectable interface,
which is a subset of GtkEditable and can apply to anything that
displays selectable content (esp. tree views and ETables).
This commit integrates EFocusTracker with EShellWindow, CompEditor,
EMsgComposer, and ESignatureManager.
It also bumps the GtkHTML requirement to 2.29.5 to utilize the new
GtkhtmlEditor:html constructor property.
