WIX UI custom files

The base contents of this folder are copied from the Wixl UI extensions. The Common.wxs file has been modified to use the custom banners. This was needed as it is not possible to pass outside strings/resources into the project as it is.

Some extra files are included from UI.wixext. The adaptation is mostly to remove the use of localization (!(loc.name)) which is not supported by Wixl. The actual strings are copied from en-US and inserted into Common.wxs.

Also, the dialogs were modified to place the buttons as the first items in the dialog, because it otherwise causes the error: "Error 2834: The next pointers on the dialog BrowseDlg do not form a single loop".

The extra files are:

• BrowseDlg.wxs
• CustomizeDlg.wxs
• DiskCostDlg.wxs
• LicenseAgreementDlg.wxs
• WixUI_FeatureTree.wxs
• WixUI_InstallDir.wxs
• InstallDirDlg.wxs
• InvalidDirDlg.wxs

The files are all licensed under the MS-RL license.
