Subject: [PATCH] ADD/CLEAN Added text_style_* methods. Cleaned modules

text_style_New  -- allocates default text style
text_style_Dup  -- allocates and copies text style
text_style_Copy -- copies text style
text_style_Delete -- deallocates text style

 NOTE that the vout_ShowText* functions
will take a p_style and copy it internally so you have
to free in the caller function. Other modules where p_style
was malloced there are now fixed to copy before calling
the sout* functions.
