Implement a script which removes the temporary files in the build directory and if choosen also the installed files in SIMPATH_INSTALL for a specific
package or all packages. If a specific package is choosen all dependent packages are also cleaned. For example the package geant4_vmc depends on vgm.
If the package vgm is cleaned also the package geant4_vmc is cleaned. Implements #46.
Add scripst to install FairRoot, AliRoot, and DDS. These three packages are not installed when running configure.sh. If one want to install these packages one has
to use the script alfaconfig.sh which will call configure.sh and will afterwards install the new packages. Add configuration option for ALFA which is needed for
some error and debug output. The new stuff is documented in README.md.
Don't check for the fortran compiler when not building the simulation engines.
The fortran compiler is only needed when building the simulation engines.
Implements #49.
