FS-3137 --resolve less of a memory leak more of a pool swelling, replaced a pool strdup that could recur with a strdup/free to avoid it

No guarantee this module still works, but it compiles again.

fix another regression from 27c6d111 this probably broke the mad boss extension

FS-3227 --resolve this looks like sane changes.  My only complaint was the formatting.  Watch for whitespace indentation by looking at the code in emacs or vi where it should be tabed properly.

FS-2877 After further review I can concede the point that we should always say partial considering how we do things.  With this commit we should at least be sending separate partial updates for each existing dialog to everyone with a subscription.  If we need to introduce more data, consolidate them etc.  We need to do it in small chunks and keep things sane.

add execute_on function so you can have execute_on_answer_1 execute_on_answer_2 execute_on_answer_3 etc

mod_say_ru now support say_string like mod_say_en. Now support channel variables gender,cases can be set in english and russian for example: <action application="set" data="cases=nominativus/>  <action application="set" data="gender=male_h"/> <action application="say" data="ru NUMBER PRONOUNCED  1001"/>
