[Plugin: ICS Calendar] Offer also ?gin-end-date% and ?gin-end-time%

Please offer also %begin-end-date% and %begin-end-time% resulting in e.g.

%begin-end-date% = 1 Apr (one day event)
%begin-end-date% = 31 Mar – 1 Apr (two day event different months)
%begin-end-date% = 1 – 2 Apr (two day event in same month)

Date format must be taken in to account for the latter situation. Something similar should be build for %begin-end-time%, e.g.

%begin-end-date% = 1 Apr 12:00 – 13:00 (start and end time on same day)
%begin-end-date% = 31 Mar 12:00 – 1 Apr 13:00 (start and end time on different days)

Implementing this will prevent odd situations as a hyphen without end-date when end-date is identical (therefore empty) to begin-date. One cannot expect end-users to implement this logic in Custom Event Format, hence it has to be offered.

Any patches via this thread are welcome.
