Correct class and table name in GrantApplicationPage.entityType.php
requested to merge webmaster_cses_org_uk/grantapplications:webmaster_cses_org_uk-master-patch-33297 into master
Fix for #197: correct the class name and table name defined in GrantApplicationPage.entityType.php to match those in grantapplications_civicrm_entityTypes() and stop CiviCRM crashing because of a non-existent class name.
NOTE: This seems to fix the immediate issue, but it may be appropriate / necessary to move the file to appear in a folder called xml/schema/CRM/Grant rather than .../Grantapplications to preserve the correct naming convention.
