FdbTop: exposed more json status data, worked on the topology screen, tweaked metrics screen, added slow/fast refresh rate, ...

- moved GetStatusAsync to Fdb.System
- exposed machine metrics, refactored other view models
- takes cluster path as first argument (note: will probably change once we add real option parsing)
Added ILRepack build step for FdbShell and FdbTop

- merge FoundationDB.Client.dll into both exe when building for Release
- tool can be xcopy deployed without versionning problems (fdb_c.dll still needs to be installed on client)
Removed unneeded references

- indentation flipflop :(
