evo patch

for evolution;

The first chunk applied for the warning itself, the rest is what I found during investigation of the warning. There were couple reference counting issues on EClient and ECalComponent, thus, for example, the client could gone before it should when creating new memo (notice the warning when you close evolution after you cancel the New Memo dialog invoked from a context menu above the memo component list).
