SQuirreL SQL Client: Version 2.6.8 released

Changes since 2.6.7:

Delete records progress dialog was being left visible after it was no longer needed in some cases.

Hidden directories are now visible to the file chooser for jdbc driver files.

Import from file to table feature now warns and asks the user to confirm that it is ok to truncate the
existing table data (The import feature doesn't yet support merging new data with existing data).

2119937: Windows EOL chars (CRLF) are converted to Linux EOL (LF).

2102894: Missing Scale Placeholder in Sql server dialect. This causes script generation and dbcopy targeting
MS-SQL server to produce decimal columns without the scale attribute (that is, decimal(7) instead of
decimal(7,5)).
