Revive build.properties, remove byte order mark

[magro]

The BOM was introduced with commit 2e97ed2. Since then the sbt version in build.properties was ignored (by the sbt launcher), in consequence the sbt launcher's sbt version was used.

If the sbt launcher was now updated to 0.13.13, the warnings described in #351 popped up.

With these changes I see the following Scalariform parser errors for the core module (didn't check others):

[warn] Scalariform parser error for /Users/martin/Development/extern/eventuate/eventuate-core/src/main/scala/com/rbmhtechnology/eventuate/snapshot/filesystem/FilesystemSnapshotStore.scala: Unterminated attribute value
[warn] Scalariform parser error for /Users/martin/Development/extern/eventuate/eventuate-core/src/main/scala/com/rbmhtechnology/eventuate/DurableEvent.scala: Expected token RBRACKET but got Token(XML_START_OPEN,<,5625,<)

These changes have also broken existing functionality:

• test:compile should automatically run it:compile and multi-jvm:compile (tested that with core/test:compile and crdt/test:compile which didn't include it:compile and multi-jvm:compile.
• test should automatically run it:test and multi-jvm:test (tested that with crdt/test which ran crdt/test:test but didn't include crdt/it:test. Surprisingly it triggered a crdt/multi-jvm:compile and a crdt/multi-jvm:test)

Thanks for catching this, I'll try to fix it.

[krasserm]

Thank you! Regarding the Scalariform parser errors, I think this is a pure sbt version issue, has nothing to do with Eventuate's build.sbt.

[magro]

The triggeredBy is broken due to sbt/sbt#1444. I'll remove the sbt 0.13.13 upgrade from this PR for now.

[krasserm]

Thanks for the update @magro. The version in build.properties is now picked up as expected:

> inspect sbtVersion
[info] Setting: java.lang.String = 0.13.11

However, I still see the Scalariform parser errors.

[magro]

Haven't looked at the scalariform stuff, how is this related to this PR? This PR now only intends to fix build.properties, I'd suggest to open another issue for scalariform.

[krasserm]

It's related to this PR as the Scalariform parser errors do not appear in earlier sbt versions. Anyway, opening another ticket for that is fine. Thanks for the PR, Martin!

[magro]

You're welcome :-) If time permits I can have a look at #356.
