Git-ignore files generated during Gradle build

These are some of the files/dirs (that you wouldn't want to check-in to
source-control) that I see after getting the gradle-build going:
Remove mail the easiest way...

On Android, the dependencies make supporting bc-mail very hard.

Previously I did an rm -Rf on the 'mail' folder of bc, but actually,
just removing the include from settings is way more Git-friendly for
rebasing.
set bc.test.data.home system property

Defining the test data path relative to project

Gradle: Specify version of JUnit to avoid unreproducible builds

Another reason for this change is that it stops Gradle from making
unnecessary trips to the network to verify if it has the latest version
of JUnit. ie, on my laptop, even after many successful builds, it was
still possible to get this error if disconnected from the internet:

--
$ gradle test

Format cert-revocation date in GMT to avoid timezone-dependent tests

In my London-based JVM, the date was actually Apr 19th, and the
asserted string in NistCertPathTest did not match.

This is an alternative to this prior pull-request, which just relaxed
the test condition to ignore the date:

Add travis-ci, hopefully without spamming the BC folks

Pretty sure BouncyCastle needs OpenJDK to build and run tests

I don't know how to register the unsigned JCE provider on Oracle JDK,
OpenJDK doesn't seem to check.

try to make travis output clearer

Hopefully fix test by installing BC provider
