Merge Date Time plugin with Clock Plugin

Date Time is an external panel plugin that can show both date and time in the panel. It supports various formats for both date and time, as it has the option to customize font for both date and time. It is a rich plug-in, but as it is an external plugin, thus it has significantly less development support.

On the other hand, a Clock is an internal plug-in that only shows time but in various layouts. But it has very few predefined time formats in the digital layout. These plug-ins have some overlapping features, and thus they should be merged into one plugin. It would be better to combine these into the clock plugin, as then, being an internal plugin, it would have good maintenance and support. This merge would reduce the redundancy of features in the panel and make the entire system more lightweight. Having two separate applications for date and time will take more computer resources than just having one.

It will also simplify the future development process. Instead of implementing the same changes in two places for the same thing, which displays time, the developers will need to make the changes in only one place. This merge will also add the capability to show the data directly on the panel, which currently needs installing an external plugin, that may or may not be pre-installed by the operating system.
