Merge pull request #3 from AbsolutelyFreeWeb/master

View time reports functionality upgrade
Fix whitespace and indentations
Fix Undefined variable notice: query_pull_timerecords

When the view_bug_time() function was called by a user without access
to timetracking information, the variable $query_pull_timerecords was
not initialized, resulting in a SYSTEM_NOTICE warning and subsequent
error #1065: Query was empty for the query: .

Now the function exits when the user does not have access.
