Versioning (#568)

- removed getClientServerAPIVersion in server (not used)
- removed rxr side (clientversion compatibility check), removed enum as well as it is now done on the client side.
- versionAPI.h
   - GITBRANCH changed to RELEASE
   - dates for all API changed to "sem_version date". Scripts to compile servers modified for this. Empty "branch" name will end up with developer for sem_version.

- Version class with constructor taking in the long version (APILIB date). Other member functions including concise(to get sem_version for new releases and date for old releases), 
  
- bypassing initial tests, also now bypasses the client-rxr compatibility check (at rx_hostname command)

- previously, compatibility between client-det was ensuring both had the same detector API (eg. same APIJUNGFRAU)
   - Now, compatibility only checks APILIB (client side) and detector API(eg. APIJUNGFRAU) (detector side) have same major version. It only does backward compatibility test. Rest is upto user to ensure. 
   - If server is from an older release, it will compare dates like previous implementation (APIJUNGFRAU from both client and det)
 
- - previously, compatibility between client-rxr was ensuring both had the same APIRECEIVER
   - Now, compatibility only checks APILIB (client side) and APIRECEIVER (rxr side) have same major version. It only does backward compatibility test. Rest is upto user to ensure. 
   - If rxr is from an older release, it will compare dates like previous implementation (APIRECEIVER from both client and rxr)

- removed APIGUI, evalVersionVariables.sh, genVersionHeader.sh (not needed or not used)

- clientVersion, rxrversion and detectorserverversion all return strings and not integers (in hex) anymore. Depending if it has semantic versioning, it will print that or the date if it is too old.

- fixed in python (strings for versions)
- check_version function in detector server changed to "initial checks" as it only checks server-firmware compatibility and initial server checks. Client compatibilities are moved to client side.
- --version gives sem_version and date? Is date needed as well. The clientversion, detserverversion and rxrversion API gives only sem_version (no date)
- - formatting
