[ticket/10751] Use sql_lower_text() in view_log(). log_data is a text column.
[ticket/10751] Add sql_lower_text() to database abstraction layer.
On MSSQL, LOWER() can only be called on bounded strings (i.e. varchar or char).
So, in order to use it on a text column, we have to convert it to an
appropriate type. We do so using the SUBSTRING function.

[ticket/10908] Download files only up to max_upload_filesize if limit is 0
Using $this->db_tools->sql_list_tables() as the first argument gives us table
names as array keys as a by-product which might be useful at some point.
