UI: Sequencer Sidebar Text-Strip Panel adjustments

The functions are now divided into two nested sub panels, since it makes it easier to navigate through the options.

The Location values are moved above the Alignment values, to avoid the confusion that the alignment values could be presets for the location.

In the menu and context menu the Text Effect strip was among the functions which had the Input sub menu visible. Text strips do not take strip inputs, so this is a bug, which is solved with this diff.
