Fix for the the "Table Data Import Wizard".

[Stanislav Dergatch]

In MySQL Workbench, the "Table Data Import Wizard" does not work properly and people have been complaining about it all over the Internet for several years now.
I encountered this issue today myself, and using the clues from the Workbench error log (at ~/Library/Application Support/MySQL/Workbench/log/wb.log) was able to fix it.

So, the problem is in the file /Applications/MySQLWorkbench.app/Contents/Resources/plugins/sqlide_power_import_export_be.py

If you replace
"with open(self._filepath, 'r') as csvfile:" with
"with open(self._filepath, 'r', newline='', encoding='utf-8') as csvfile:"
at lines 421 and also line 501, the import starts working properly.

(But the proper fix should perhaps take into account "encoding" setting selected by user in wizard screen dialog.)

Though it is still way slower (perhaps ~100 times) than using the "load data local infile" sql command. (But to get that one work also was not an easy task...)

Just FYI...
