Keep an element editor text field in place when its width changes

Browse Source 
In the element editor, changing the width of a right-aligned or centred
dynamic text field (with the width box) moved its aligned edge: the
field always grew or shrank from its left edge, so a right-aligned
field's right edge moved. PartDynamicTextField::setTextWidth() now
keeps the point chosen by the alignment in place, with the
prepareAlignment()/finishAlignment() pair setPlainText() and setFont()
already use. Not while the field is read from the .elmt, whose saved
position is the one to keep.

No file format change.

chosen by its alignment stays in place, as when the text changes: a
right-aligned or centred field no longer grows to the right only, and
undoing a width change puts it back where it was.
