Summary:
Change name of 'grid' to 'table' for matching on common ui naming
and avoiding confusion with 'gengrid' and 'grid view'.
grid will be introduced as grid image view after.
Test Plan:
checked make & make install
checked make check - there are errors but not related with these changes.
checked make examples - there are errors in cxx but not related with these changes.
checked make discheck - failed
test in elementary_test with Efl.Ui.Table and Table_static.

make examples now builds all c++ examples but some of them are in fact
empty skeletons. Those either need some c++ love or the final eo api to
be ready (eg. menu, popup, ...).
I removed some examples that don't have an exact equivalent in EO since
the widget is legacy only.
