fix a few places that used the copy of a module/project fromt the _rm_ array after the array itself was updated

* use global variables
* use arrays instead of objects

This change has the risk of breaking the previously working version, even on php5

added releasemonitor module version number to page display for easier support;
change static variable names to follow _modulename_ format;

use simpler/hopefully faster syntax for determining the first character of a variable - $var[0] instead of drupal_substr($var, 0, 1)

fix display of modules not queried on settings page;

remove the major/minor upgrade notices which are redundant since adding the download buttons (and make the page busier than it needs to be)

change settings page to be consistent (admin/settings/releasemonitor) in Drupal 4.7 and Drupal 5;

fix Drupal 4.7 settings requery;

always give the user the option to turn it on or off;

but still needs work with subprojects (like ecommerce).  That might have to
wait for the fully implement project.info files...

change hook_help description to use releases instead of versions;

(still a couple of todos, but I wanted to get this into cvs)
