Julia and Python apps fail GPU compilation

[rloekvh]

There are a few issues compiling GPU code with Julia or Python apps.

1. Compilation will fail with 4 errors of the form

   gpuFbou.cu(32): error: identifier "gpuFbou1" is undefined

In the generated file gpuUbou.cu in the app folder, the function is called kernelgpuFbou1, not gpuFbou1. These functions are generated in Gencode/gencodeface files. They are generated correctly in the matlab version, but not in Julia or Python for versions 0.1-0.3

2. After that, an error appears that opuApp.a does not exist. This is due to missing lines in compilecode.jl and compilecode.py. Line 110-113 in the Julia code is

   elseif app.platform == "gpu"
   run(string2cmd(compilerstr[3]));
   run(string2cmd(compilerstr[4]));
   if app.mpiprocs==1
       run(string2cmd(compilerstr[7]));
   else
       run(string2cmd(compilerstr[8]));
   end
   end

   while the same code block in matlab is

   elseif app.platform == "gpu"
   eval(char("!" + compilerstr{1}));
   eval(char("!" + compilerstr{2}));       
   eval(char("!" + compilerstr{3}));
   eval(char("!" + compilerstr{4}));
   if app.mpiprocs==1
       eval(char("!" + compilerstr{7}));
   else
       eval(char("!" + compilerstr{8}));
   end
   end

   The Julia code also needs to run compilestr(1) and compilestr(2). Same holds for Python
