Changelog for webdriver-0.3

#Change Log

hs-webdriver 0.3

2 typeclasses were introduced. All WebDriver commands are now overloaded on WebDriver class, so that monad transformers with a WD base can be used conveniently.
The MonadState instance of WD has been removed and replaced by SessionState.
The Firefox profile code has been generalized to work with either Opera or Firefox profiles. A phantom type parameter is used to create a distinction between the two. See documentation on Common.Profile and Firefox.Profile to learn about the specific changes that were made.
FFLogPref is now removed and replaced by the LogPref type, because both Firefox and Opera config use the same logging preference values.
Several new modules have been created, including: Capabilities, Monad, Classes, Exceptions. Many of the definitions have been moved around, but the export lists of the pre-existing modules are the same.

Various issues with the serialization of capabilities meant that Chrome, IE, and Opera weren't able to startup correctly with default capabilities. This is now fixed.

FailedCommandInfo changed so that it stores a WDSession rather than just a Maybe SessionId, thus providing server host and port information as well as the session ID.
As a result, mkFailedCommandInfo is now String -> WD FailedCommandInfo, since it requires access to the WDSession state.
HTML5StorageType changed to the more accurate WebStorageType

general documentation improvements
the uploadFile, uploadRawFile, and uploadZipEntry functions, which support uploading file contents to the remote server

getWindowSize, setWindowSize, getWindowPos, and setWindowPos have all been deprived of their WindowHandle argument. This is due to the fact that using unfocused windows with those commands causes undefined behavior.
