Add Catalan localisation

[J0anJosep]

I would like to make Catalan language available in Julius and Augustus. This PR modifies the corresponding files and adds the Catalan translated strings for Julius.

I have tested it and the only problem I have found so far is that the middle dot is rendered as an empty space. So, instead of "cancel·la" it is shown as "cancel la":

If this could be amended, please, could you tell me what should I do so it can be solved in this same PR?

Thank you very much!

I think this could be fixed by using the dot image but a bit elevated so it would provide the desired result, however I don't know enough about the text encoding and font rendering processes to do that.

Hopefully @bvschaik has a better idea on how to do it.

Crudelios' suggestion might work, I'll look into that.

The more important question: did you also translate the game itself into Catalan? (the two .eng files) If so, please attach them to this PR, so we can test the code.

I looked into displaying the middle dot, you can do that with the following patch:

Yes. It works perfectly. Thanks!
