This line was removed in a (foolish) commit
to development. It should remain in place,
otherwise the displayed hit count is messed
up when the search input changes.

Previously, hitCount was increased every time
a new batch of results was loaded.

added GitlabService.java to offer basic gitlab api functionalities like check if repo exists etc. , added check in StatisticsResource to avoid people sending get requests with IDs which not exist and therefore create lots of trash entities

layouting

The new search-dropdown component HTML still
includes references to the search component.
Put these in a comment to allow compilation.
Since the component is not in use,
this problem only needs to be addressed if this
dropdown is used in the future.

authors is no longer a valid keyword.
In this commit the corresponding functionality
is removed. It will be replaced in the future.

keywords was renamed to keyword.
Change some variable names accordingly.
(Some changes might be unnecessary and could be reverted.
I prefer continuing the usage of keywords,
since it is a more logical name for a list of keywords.)

programming_languages was renamed to
programmingLanguage.
Most corresponding variable names have not been changed.

natural_languages is now called language.
This attribute does not seem to be in use.
