EXPLAIN SELECT should show what engine is going to be used for temporary tables

Registered by Laurynas Biveinis

Currently EXPLAIN SELECT only shows that temp tables are going to be used, but does not show what kind of engine (MEMORY or MyISAM) is going to be used. This feature would add the type of engine to the EXPLAIN SELECT output.

Optionally it is also possible to add short explanation of why MyISAM table had to be used instead of MEMORY.
