doc Vcursor Importtext + Addrecord

[Olivier]

in V4RB reference, page 110,  "Vcursor", the description of method 
"Import_Text" indicate the old "ImportText" on the place of new 
"Import_Text".

Same problem in the example.

In the description of the parameters, the new parameter 
"inHasColumnHeader" is not put in brackets to indicate that it is 
optional while the others parameters (delimiters) are now, them, 
indispensable.

page 107, the description of the method "addRecord" does not indicate 
of what consists the returned integer.

in the example, it is old "add" what is used on the place of 
"addrecord".
