78, add SQL TRIM function

Added basic TRIM function that trims whitespace.

Adding complete TRIM('x' FROM Name) syntax would be problematic because
of special JavaCC parsing for FROM keyword that sends parser into
a different parsing state to enable table names containing special
characters, such as foo-bar.

Added unit tests TestCsvDriver.testTrimFunction,
extended TestSqlParser.testParsingQueryEnvironmentEntries
Fix "resource leak: f is never closed" Eclipse warning

Fix unit tests to always close files in a try-finally block at end of test.
Update paths for where.jj, resources, test classes
Next version is 1.0-20
101, fix parsing of dates containing month names

Use SimpleDateFormat to parse dates containing month names, day
names, or other non-numeric format.

Added unit tests TestStringConverter.testParseDateNamedMonth,
testParseDateNamedDay.
