avoiding an unneeded context creation in TextMorph - aligning with StringMorph
avoiding use of Point to describe the row/column of a slot, IMHO that's an overkill and slightly confusing. Using coffeescript's "destructuring assignment" instead.
fixing the fact that the de-selection mechanism was preventing the possibility to invoke the "doIt" on the current selection...
factoring-out a "spawnInspector" function which was common to Morph and TextMorph
