Section for UseSAK in tdmrc

Hi all, during the fixes d9f52880 and ea6a2153 I noticed that in a7e7483a was changed the section in which the is specified UseSAK in the configuration file - it was [X-*-Greeter] now is [X-:*-Greeter]. This change makes sense, because SAK can be used only on the local displays. However kcontrol module for tdm still saves the UseSAK settings in section [X-*-Greeter] as well as both other cases looking for UseSAK settings in section [X-*-Greeter]. I suggest to fix all three cases, to use the section [X-:*-Greeter]. What is your opinion? -- Slavek
