[Yum] yum dependency handeling

[Rick Thomas]

Default behavior should be to give an error message and refuse to 
do anything -- same as now.  The error message should name an 
option (perhaps: "--allowincompleteupdate" or something like that) 
that the user can apply that will disable the error and "do what's 
possible" to update what it can.
