Spellchecker engines

There are 3 types of spellchecker implementations, that needs to be required/included individually.

PSpellShellUses the command line/shell executable version of PSpell. If this option is to be used in Windows it is necessary to add the path to the "aspell.exe" file to the Windows Path environment variable. In Windows XP this is done by going to Start > Control Panel > System. Select the Advanced tab and click on the "Environment Variables" button. Under "System Variables" add to the Path variable the path: "C:Program FilesAspellbin." Do not include this path in $config['PSpellShell.aspell'] because everything after the space between "Program" and "Files" will be ignored.
GoogleSpellUses a remote google service. Remember this service might be unavailable if google decides to make it non public.
PSpellUses the built in PSpell module in PHP. (Needs to be compiled in)
