Rename the library to [lib]combine

[agarny]

With [lib]Combine, a CMake file called [lib]Combine-static-config.cmake gets generated. Such a CMake file cannot be found on a case-sensitive system (since that kind of filename should be all lower case). Instead, a CMake file called [lib]combine-static-config.cmake should be generated, hence the suggestion to rename the library to [lib]combine, not least so that it's consistent with libSBML, for instance.

The problem that i see, is with this change, all packages that ever used libCombine will have to change. So far they would have had a fallback statement using the CONFIGS flag on case sensitive filesystems. But with the PR the number of variables to test would have to be doubled (checking for [lib][c|C]ombine), to test. Here is how other projects were importing in the past:

find_package(${COMBINE_LIBRARY_NAME} CONFIG QUIET)

if (NOT ${COMBINE_LIBRARY_NAME}_FOUND)
  find_package(${COMBINE_LIBRARY_NAME} CONFIG QUIET
  CONFIGS ${COMBINE_LIBRARY_NAME}-config.cmake
  PATHS ...
  )
endif()

Fair enough. I have my own fork of the library, so I am fine. (Feel free to close this issue and the corresponding PR.)
