Notes Functionality - Add/Edit/Browse Notes for a Contact

Extend and modify current Notes functionality as follows:

• Add Contact screen - no change

• Edit Contact and View Contact screen:

• Contact Notes region displays list of 2 most recent notes in date order descending
  + If no notes, just show message - "There are no notes for this contact."
• Display Notes in table with 3 cols (no column header needed here)
  + col 1 = truncated note text (can use smarty var|truncate in .tpl for this), linked same as 'View' (note)
  + col 2 = date (last modified)
  + col 3 = View | Edit links (see below for link actions)
  + later, we'll include another column for "By" (user who entered the note) - don't have that info yet

• Include these links below notes summary (see below for link actions):
  + "New note" - (always shown)
  + "Browse all notes..." (only show this IF there are more than 2 notes for this contact.

• Browse Notes + Add/Edit/View Note:
  + This should be setup as a new 'local task' under View Contact (in contact.module)
  + Page has four modes

• BrowseOnly - just show summary list of notes for this contact, i.e. 'selector'
• BrowseAdd - simple Add Note form on top, selector below
  (cursor should focus on Note field onLoad)
• BrowseEdit+noteID - simple Edit Note form on top. Selector below.
  (cursor should focus on Note field onLoad)
• BrowseView+noteID - Box on top displays entire text of referenced Note. Selector below.
  + On Add/Edit Save, put up status and return to BrowseOnly mode
  + Summary list is selector-style table of all notes
• 2 columns, as above but with column header
• Default sort is Date descending. Date column is 'sortable'.

• Directory Structure
  + Functionality dealing with a Contact's Notes (like Browse Notes) goes under Contact
  + Add/Edit/View a Note functionality goes in a new Note tree
  e.g. templates/CRM/Note/Edit.tpl and View.tpl
  (we'll switch to using Edit.tpl rather than Add.tpl as naming convention for Add/Edit templates)
