Added DirVerify (works in PageEx directory) and GetInstDirError. If `DirVerify leave' is used, the next button will not be disabled if the installation directory is not valid or there is not enough space and a flag will be set instead. You can read that flag using GetInstDirError in the leave function of the directory page. A value of 0 means no error, 1 means invalid installation directory and 2 means not enough space. This allows you to handle those errors on your own.
