Removes need to check if the repository is valid before
each native API call and also removes calling into the
native-side if no repository can be opened for the project
page.
This is required for the property-list bundle to highlight
.plist files that maybe in XML or non-XML formats.
Also specify the cached buffer disk contents to grammarForFilePath
so fs.read doesn't need to be called again if the contents are
already read.
Previously the status was fetched twice, once for
if modified and once for if new.
Now the flags are fetched once and Git now provides
helpers to check the status flags directly for
modified and new status.
A confirm dialog is now displayed whenever a session
with a dirty buffer is closed so dirty sessions can now
be processed when 'editor:close-other-tabs' is fired.
Previously only the active editor session was prompting to
save dirty buffers before closing. This caused the confirm
dialog to not display when closing from a tab since the
Editor.destroyEditSessionIndex is used there.
Previously window.shutdown() was called multiple times
if window.close() was called since the shutdown handler
was also fired in the native window controller.
This prevented proper serialization of the RootView
from occurring when then window was closed via meta-w or
meta-W since it was called a second time when already
empty of packages and editors.
Previously these weren't displayed since event the
documentation loop stopped at the document element and
window events weren't included even though they are
applicable for the currently focused element.
Previously if null was returned for the end of word position then
it was interpreted as 0,0 which would select the entire contents
before the current word instead of the current word.
