Spell-checker

This is a continuation of the previous project which was worked on. A crucial part of the requirements was not met. The suggestions were included and worked fine, however, the requirement is that the user be allowed to select the misspelled word from a click action which only then should it display the list of suggestions for the word selected. Misspelled words should still be highlighted, but should not require the user to correct the spelling for any words, just the words selected by user. This is only required for the richtextbox on the form, not necessary for the normal textbox.
