M core/html_api.php
(html_button_bug_monitor):

• No need to check for private threshold, since if the current user is below
  the threshold, (s)he won't be able to view the defect in the first place.
  Also if we take it into consideration we shouldn't assume that private
  threshold is > than monitor threshold.
  (html_button_bug_unmonitor):
• Added the missing td tags.
  (html_buttons_view_bug_page):
• A new function that prints out all the buttons that should appear on the
  view bug pages. This is now called from within both simple / advanced pages.

M bug_view_advanced_page.php
M bug_view_page.php

• Both pages modified to call html_buttons_view_bug_page() rather than
  duplicating the same code.
