Use a Webview to show weekly or a monthly views

When entering an input for opening a journal page, a pick list could show all already existing journal pages (e.g. last 10 and next 5 days). Next to each entry, the number of (open) tasks and attached notes is added.

Example: (today is 11-24)

_______________________________________________
|  Enter day or memo (with flags), or pick one  |
-----------------------------------------------
11-17 (Thursday) 0/3 Tasks, 2 Notes 
11-18 (Friday) 1/2 Tasks
11-21 (Monday) 5/8 Tasks, 4 Notes
11-22  (Tuesday) 2/2 Tasks, 1 Note
11-23 (Wednesday) 1/1 Task
> 11-24 (Thursday) 
11-25  (Friday) 
11-28 (Mondy)

VSCode only supports input or selection, no combobox. Not sure how to handle this for now (see microsoft/vscode#426)

Renamed the ticket, will be solved via webviews now
