Increased date format field sizes
Merge pull request #328 from Elte156/new/date_format

Increased date format field sizes
A new timesheet entry can be added to multiple users. (closes #39)
Include project expenses on an invoice. (closes #61)
Refactored creation of sublist annotations. (closes #132)

Using json_encode we solve the escape issue and have less lines. Only
difference is that the annotation variables are now object and not
arrays. But that makes no difference.
Automatically open entry after the recording was stopped. (closes #163)

This has been implemented as a user preference and is off by default.
