Avoid importing java.io.File (the idea is to simplify verifying the file system abstraction is really used everywhere)

Lob in database: storing lob objects was not correctly synchronized. This was specially a problem when using Connection.createBlob() / createClob().

The NIO cleaner hack wasn't working as expected, because the clear method was called instead of the clean method. This has been fixed. Please note this hack is not enabled by default, to try it you need to set the system property "h2.nioCleanerHack" to true.

Added support for modulus operator in expressions

Issue 288: Some right outer join queries failed to produce the correct result or threw exceptions such as "column x must be in the group by list". Some right outer joins with invalid column referenced (typos) threw a NullPointerException instead of "column not found" exception.

New database setting EARLY_FILTER to allow table implementations to apply filter conditions early on.

Cluster: in a two node cluster, if cluster node stopped, and autocommit was enabled, then changes on the remaining cluster node didn't get committed automatically.

- the dialect detection will most likely be based on the URL, not on the class name
- 'declaration' is a much too generic term for 'set column = value'
- method names should start with a verb (getTableName instead of tableName)
- remove redundancy and unnecessary formatting in Javadocs (keep it as simple as possible)

Issue 265: Linked tables: auto-reconnect if the backside connection is lost (workaround for the MySQL problem that disconnects after 8 hours of inactivity).

Database-level connection settings could only be set in the database URL, but not using the Properties parameter of DriverManaget.getConnection(String url, Properties info).
