Fix password issues in IntelliJ 12

I noticed that Intellij IDEA 12.1.4 (Community Edition) was not properly remembering my github login.

I was able to fix it using these steps:

1. Close Intellij
2. Delete the file security.xml from .IdeaIC12/config/options
3. Start Intellij

The .IdeaIC12 folder can be found in the home directory of your user account.
