Script to update the ui.xml settings file for FBReader 0.8.14.

The file ui_orig.xml is the version already installed by default.

The file ui.xml is the version you want to use from now on.  It will become the new version for FBReader.

As a record, the existing ui.xml will be copied into the file ui_<DATE>.xml.  
Note that DATE is the current date, i.e. when the file was removed from FBReader's registry.

If you ever want to restore the original version, just copy ui_orig.xml to ui.xml.
