Cleanup: rename to BLI_path_cwd to BLI_path_abs_from_cwd

This is now more clearly a function that makes the path absolute
using the current working directory.

Merge branch 'master' into greasepencil-object

Fix status bar message showing saved when saving failed

Resolves the following issues:

- For the first time you save a .blend file, there was no feedback.
- If the file fails to save (eg "No space left on device") the status
bar message replaces the error with an invalid "Saved" message.

While there is a popup, the user may cancel it with mouse motion
and be left with the status bar message saying the file saved.

Fix missed depsgraph update after undo in some cases

Forgot to take into account legacy DEG_id_tag_update with zero flag.

Debugging: change Undo/Redo redraw timer to include dependency graph update

This is often the slowest part and was not counted before.

Support multiple panels of the same type

The name for the uiBlock associated with a panel was just the panel type's
idname, so the old block found at the start of drawing was the same for
every panel of a certain type.

Panel blocks for list panels are now named with the list index appended
to the end of the name. The panel list is also rebuilt when reordering
panels of the same type.

UI: Language Selection Changes

Removal of 'Translation' checkbox. Enable translation options when selecting non-English languages.
