Fix Alto on Linux

[FilipToth]

• Add build aoi and aoc shell scripts
• Make sure everything works

[FilipToth]

Most of this is done on my local branch.
Although, I'll have to to introduce a better way of starting processes and then displaying the out of dotnet run in the aoi.

I'll try executing the emitted program, forwarding stdout to a file and then reading the file from the aoi to get the output.

dotnet run >> /home/%user%/.Alto/outp

Note: also have to clear the outp file after we read from it.
