Remove compile time dependency on bouncycastle

[Akirathan]

There are unnecessary compile time dependencies on bouncycastle. Let's remove them.

In text-buffer, SHA-3 is used and it seems unnecessary. Let's only use SHA-1 from JDK. Moreover, as declared in build.sbt, text-buffer depends on bouncycastle JDK1.5, instead of the newer JDK1.8.

The dependency on org.bouncacastle in runtime can be removed via something like this:

Note that we need runtime dependency on org.bouncycastle modules because python-language-23.1.0 depends on those anyway.
