Title: Remove legacy code from JApplicationHelper

Removing some legacy code from JApplicationHelper:

- In method getPath, replace use of JRequest with JInput and remove path check for CMS 1.5 plugin path
- In method parseXMLInstallFile, remove check for legacy install tag in extension XML and remove mosinstall tag from `$data['legacy']` (can this be completely removed?)
- In method parseXMLLangMetaFile, correct the comment for the valid XML root tag
