For calendar entries containing a year (e.g. DOB) in the title, the age
can be calculated.
Example before:

after:

Achieved by adding a new keyword `transform` to customEvents
```
customEvents: [
{keyword: 'Geburtstag', symbol: 'birthday-cake', color: 'Gold', transform: { search: '^([^\']*) \'(\\d{4})$' , replace: '$1 ($2.)', yearmatchgroup: 2}},
{keyword: 'in Hamburg', transform: { search: ' in Hamburg$' , replace: ''}}
],
```
and therewith obsoleting `titleReplace`; a backward compatibility part
is already included.
If `yearmatchgroup` is unset, behaviour is as in previous code (some
additions to which RegExes are accepted, though)
If `yearmatchgroup` is set, it is considered the RegEx match group id,
which will be used for calculating the age.
> - If it includes major visual changes please add screenshots.
NO
> 3. Please run `npm run lint:prettier` before submitting so that style

Fixes#3095.
Param `hideOngoing` is by default set to `false`, but the event
filtering handles `full day` & `non-full day` events inconsistently. For
`non-full day` _ongoing_ and _upcoming_ events are returned, while for
`full day` only _upcoming_ events where returned.
Refactored some methods in calendar module:
- move methods into own file
- dont call shorten method from titelTransform because why? just call
them after each other.
- added tests for util methods
- cleaned up other tests
