add logger/compiler class (#680)

* implement make install
set CMAKE_INSTALL_PREFIX e.g. to /opt to install to /opt/hyperion
set ENABLE_SYSTEM_INSTALL to ON to activate installation
after compiling use
make install
or
make install/strip
(for performance/size optimized binaries - compile in Release to get best performance)

* cleanup cmake files
use
cmake -DINSTALL_PREFIX=/opt/hyperion ..
to install all files to hyperion or
cmake -DINSTALL_PREFIX=/usr/
to install to usr. install folders are linux standard. bin go to bin folder and additionals (effects) go to share/hyperion

* add uninstall target - be patient with that, this will remove files from your system
install service files to share/hyperion - if you want to use them you have to make a symlink to your location of service files

* optimize build release script
install service files into hyperion share folder (services not activated, this must be done by distribution package script)
initial support of cmake option -DPLATFORM= option. This selects platform specific cmake flags. no need for -DENABLE_... options (unless you want some special things)
automatic detect for apple build

* update submodule

* fix cmake error when no platform is given

* initial support for deb,rpm and tgz packages - no usefull content atm!

* make packeages contain usefull stuff

* add license
make packes more functional. package specific install missing yet

* implement debian postinstall

* disable rpm generation until it has a working state

* add hypercon compat

* add posibility for multiple config files. first one found is taken

* remove hyperion comaptlayer
services is not started automaticly

* rework debian postinstall:
- remove /opt compatibility complety. This makes more trouble as it is usefull
- when hyperiond already started, restart it
- cleanup

* add deb package dependencies

* wipe out last support for /opt installation

* change default effect path in config to /usr

* revert service files and config files

* remove last occurences of ENABLE_PROTOBUF
fix cmake warnings and make it ready for cmake 3
fix refactoring of hyperiond.cpp creates no objects for network services

* all arguments via reference ...

* fix xbmcchecker not working

* add logger class

* - profiler must be activated with ENABLE_PROFILER, otherwise an error will raise
-> this should prevent profiler gets into release code

* fix profiler
