Incorrect ajax calls when installed in subfolder

Created by: hamacekh

Our mantis is located in subfolder e.g. https://www.somesite.com/mantis . When creating new issue, ajax calls are called aginst https://www.somesite.com/plugin.php?page=SearchRelatedIssue/search That is incorrect. Correct endpoint is probably https://www.somesite.com/mantis/plugin.php?page=SearchRelatedIssue/search
