Query for environment to include in `LaTeX-env-figure'

[Arash Esbati]

Hi all,

when inserting a table environment with 'C-c C-e table RET',
`LaTeX-env-figure' inserts the floating environment 'table' and then
inserts the tabular environment stored in
`LaTeX-default-tabular-environment' (the relevant part starts here[1]).

I like the idea, but `LaTeX-default-tabular-environment' is notoriously
the one I currently don't want.  Should we change this part a little in
order to give users a chance to pick up what they want?  I'm thinking
about a change like this:

Over the time, we have to adjust the regexp, but it should get us
started.  Any comments welcome.

Best, Arash
