Support for more ruby-like method names

[rubyFeedback]

Hello.

For example, to add a tooltext to a button, we may have this:

button.tipText = ' Push Me! '

We do not have:

    button.tip_text = ' Push Me! '

Would it be possible to add the latter?

Reasoning:

In ruby we do not use the above C++ style of method names, but instead
typically use the downcased variants.

Note that I am not suggesting that Lars does this - I am mostly asking
whether it would be ok to add these aliases to the code-base of fxruby,
e. g. whether Lars would be ok with that.

We can work around the above, I assume, if we add custom modifications
("monkey patching" or "duck patching"), but then we'd have to distribute
that code as well, which is why I think it would be better to have this available
in fxruby as-is already. (With monkey patching we can easily add an alias,
but distributing this then becomes a bit harder, since we may have to distribute
this to other users.)

Sorry for my late answer! But yes, I'm open to add such aliases.
