[Devtools] New platform-installer component for Platform installer in JIRA

[Alexey Kazakov]

Hi,

I've created a new component "platform-installer" in JBDS JIRA [1] for 
the Platform Installer issues.
The old "installer" component will be used for our old JBoss Developer 
Studio universal installer.
It will help us to plan our DevStudio and Platform Installer sprints.
