Expose API Facades to be Consumed from the Custom UI

[ThuF]

Create HTTP API facades for the following requests (made in chronos-ext/ui/common/api.js) and move /services/v4/js/chronos-app/gen/api/... requests to /services/v4/js/chronos-ext/services/...:

1. createProjectTask(): POST @ /services/v4/js/chronos-app/gen/api/Projects/Task.js
2. updateProjectTask(): PUT @ /services/v4/js/chronos-app/gen/api/Projects/Task.js/${id}
3. deleteProjectTask(): DELETE @ /services/v4/js/chronos-app/gen/api/Projects/Task.js/${id}
4. createTimesheet(): POST @ /services/v4/js/chronos-app/gen/api/Timesheets/Timesheet.js
5. updateTimesheet(): PUT @ /services/v4/js/chronos-app/gen/api/Timesheets/Timesheet.js/${id}
6. deleteTimesheet(): DELETE @ /services/v4/js/chronos-app/gen/api/Timesheets/Timesheet.js/${id}
7. createTimesheetItem(): POST @ /services/v4/js/chronos-app/gen/api/Timesheets/Item.js
8. updateTimesheetItem(): PUT @ /services/v4/js/chronos-app/gen/api/Timesheets/Item.js/${id}
9. deleteTimesheetItem(): DELETE @ /services/v4/js/chronos-app/gen/api/Timesheets/Item.js/${id}
10. getTaskStatuses(): GET @ /services/v4/js/chronos-app/gen/api/Configurations/TaskStatus.js

The will allow the enforcement of Admin role for the whole chronos-app module, instead of just the UI part as of now (chronos-ext/access/admin.access)
