Bug 6727 - Change on exporting and importing csv to deal with spurious CR/LF

Browse source 
Function _export_table_csv modified to remove CR/LF in the data
from the database to built a correct csv file.

Function _import_table_csv modified to deal with CR/LF in the data
field. When a line is found with an unproper end (a data field has not
end quote), it's concatenated to a temporary buffer until the next
line ends ok and then it's proccessed.
