dde communication example app

Created 16bit windows application which does pretty much the same thing as the
yukon installer.
First it creates atom(s) for application & topic. Since both are: PROGMAN only
one atom is created.
Progman is started from button PM_Start.
When PROGMAN is running WM_DDE_INITIATE message can be broadcasted with button
DDE_Init.

When WM_DDE_ACT message received and is being handled. 
Atoms are extracted from lparam and stings related to atoms are retrieved with
GlobalGetAtomName.

In Windows2000 this seems to be working.
Atoms are the same which were created and GlobalGetAtomName returns 7, which
matches to lenght of PROGMAN.

In Wine10.16, atoms seem to be zero, which leads to failing of
GlobalGetAtomName calls.
