Removed suplicate key: :javac-options

Building storm causes errors due to a duplicate `:javac-options`
entries in the `storm-core/project.clj`.
```
Caused by: java.lang.IllegalArgumentException: Duplicate key:
:javac-options
```
I have merged the `:javac-options` into a single entry.
Could not find artifact org.jgrapht:jgrapht-core:jar:0.9.0

Artifact `org.jgrapht:jgrapht-core:jar:0.9.0` does not seem to exist in
any of the referenced repositories. The following artifacts are

k~jgraph
t-core):

I have changed the entry in storm-core/project.clj to use
0.9.0-SNAPSHOT.
