Add OSGi headers to JAR manifest parser

[mkem114]

Makes the IDE squiglies more useful since common headers will be recognized

I think similar functionality is provided by an OSGi plugin
https://plugins.jetbrains.com/plugin/1816-osgi
Here's the similar class:
https://github.com/JetBrains/intellij-plugins/blob/d4c63a37d1f3af1f15bb55406a58ecb61fade118/osmorc/src/org/osmorc/manifest/lang/header/OsgiManifestHeaderParsers.java

I don't feel that we need to duplicate it right in the IntelliJ Community.
Though probably we need to support more headers in OSGi plugin. Probably, the PR should update that class instead. @trespasserw please take a look, as I see that OSGi plugin was maintained by you.

Did the performance and bugginess problems with that plugin get resolved? Honestly seemed kinda dead.
