Merge pull request #318 from gregors/typo

fix typo
make sure we require arjdbc instead of just arjdbc/jdbc from adapters
load out raltie from arjdbc instead of activerecord-jdbc-adapter
thus it will work consistently even if only a specific adapter gem is specified in Bundler's Gemfile
support auto-loading of adapter gems e.g. when specified in a Gemfile
no need for a ArJdbc::Version module simply use VERSION; at 1.3.0.DEV
run more (simple) tests for (almost) all + improve partial updates test
(native) connection #columns #columns_internal expects string table_name
[db2] (finish up) XML column support
[mysql] version + support_"feature" (as Rails); align sql type mapping
groupd schema dump tests + generic schema dump tests (from Rails)
jdbc_connection unwrap parameter for unwrapping (pooled) connections
avoid unitialized instance var warning
some more schema_dump tests + standalone schema tests for postgres
(yet again forgot that) some schema tests won't work on older AR versions
make sure update_sql is public in mysql adapter (4 Rails compatibility)
review dirty attrs tests due "artificial" failures on 2.3 + sqlite3 schema dump
