Changes from 1.4.2 to 1.4.3

• Fixed multiple issues introduced in v1.4 which in some situations would result in unnecessary CPU consumption of up to 4% while the application was left idle in the background. (When nothing is playing, its CPU usage should drop down to 0.0% as shown in Activity Monitor, and should remain there.)
• Fixed bug introduced in v1.4: application prevented system from sleeping when opened with no player windows.
• Fixed bug introduced in v1.4: the "Additional mpv options" table (in Settings… > Advanced) incorrectly overwrote the Value column when new text was saved into the Name column.
• Fixed bug introduced in v1.4: tab navigation broken in the Bindings table (in Settings… > Key Bindings).
• Finished adding undo/redo support for cell edits in the "Additional mpv options" table (in Settings… > Advanced). (Support was added in v1.4 for undo/redo of other operations like add/move/delete, but "update" was somehow overlooked).
