Keystore paths contain many backslashes on Windows

Description of problem:
When you set up JSSE server keystore, JSSE client truststore, SSL keystore or password vault keystore, the paths to these keystores on Windows will contain four or eight backslashes in a row instead of just two. Right now this behavior does not seem to break any functionality, however, I think it should still be fixed.

Version-Release number of selected component (if applicable):
6.1.0 ER3

Steps to Reproduce:
1. JSSE server keystore
2. JSSE client truststore
3. SSL keystore
4. password vault keystore

Actual results:
C:\\\\\\\\BRMS-6.1.0\\\\\\\\jboss-eap-6.3

Expected results:
C:\\BRMS-6.1.0
jboss-eap-6.3

Additional info:
The same problems will probably be found in BPMS installer. Maybe even more, since unlike BRMS there are also JMS SSL keystores configured in BPMS. But BPMS installer has not been fully tested on Windows yet.
