Remove platform specific project files

[pattacini]

@rezaahmadzadeh we don't commit project files that are platform specific (e.g. Visual Studio *.sln files). Consider cleaning up the repo.

Also the directory name exe is too window-ish...

@rezaahmadzadeh take a look at this: https://github.com/robotology/funny-things

The structure I always use is this (obviously, take this with a grain of salt, everyone has his own preferences):

/root
    CMakeLists.txt
    /app
        CMakeLists.txt
        /conf
        /scripts
    /build (aka "where all the sh*t happens" - NOT VERSIONED)
    /lib (if needed)
        CMakeLists.txt
        /include
        /src
    /modules (or src)
        CMakeLists.txt
        /module1
            CMakeLists.txt
            /include
            /src
        /module2
            CMakeLists.txt
            /include
            /src
