ApplicationPath is tied to exec location #27

Hello,

As per https://github.com/ptitSeb/Serious-Engine/issues/5#issuecomment-465722224 resources path should be independent from binary location Looks like GetExecutablePath shoild be replaced with GetUserDirectory https://github.com/ptitSeb/Serious-Engine/blob/master/Sources/Engine/Engine.cpp#L274 in order to use SDL's Prefs

It is pain to extract game resources into separate folder as the game do some manipulations in the same dir. For most painful things I apply hacks (sorry for ugly bash code):

Add fallback to default lib location if nothing found:

'@@ -107,0 +108 @@\n'\
'+        if (module == NULL) DoOpen(fnm.FileName()+fnm.FileExt());\n'\
| patch target/Sources/Engine/Base/Unix/UnixDynamicLoader.cpp &&

Use GetUserDirectory instead of GetExecutablePath

printf ''\
'@@ -274 +274 @@\n'\
'-  _pFileSystem->GetExecutablePath(strExePath, sizeof (strExePath)-1);\n'\
'+ _pFileSystem->GetUserDirectory(strExePath, sizeof (strExePath)-1);\n'\
| patch target/Sources/Engine/Engine.cpp

And also those two (as a consequence of previous): The game creates log file in dir defined by GetUserDirectory - log file can't be disabled For some reason the game attempts to open libEntitiesMP.so (invocation lfomethere from resource loading code) - empty file should be created bash touch "$UserDirectory/Bin/libEntitiesMP.so"
