Decide which ruby versions to support

[isuruf]

In travis, we test,

• 1.9.3
• 2.0
• 2.1
• 2.2
• 2.3.0

We initially included these because these were the ones supported in NMatrix I think.

Since official support for 1.9.3 is stopped including security patches, I'm okay with dropping 1.9.3. What do you think?

I'd boldly say that 2.0 should go away too. It is already deprecated, and 2.1 have significantly superior features (keyword arguments and refinements), and as SymEngine is more than any other SciRuby project needs clean modern API, ...

I'd still say go with ruby 2+ for now and then drop support by the end of the year.

Since 1.9.3 is the only one that is making us take extra effort to write compatible code, that should be the one to go first. One of the tests for 1.9.3 fails on OS X too.

For 2.0 we haven't had any problems yet, I think. Let us keep the tests for 2.0 for now and when we come across another issue where something is not supported in 2.0 we can drop it then.

Let's drop 1.9.3. since it doesn't receive security patches. We can probably drop 2.0 as well, but we can also be conservative and drop it a bit later.

Seems 2.0 also doesn't receive security patches. We should drop 2.0 as well.
