Execution handling

[Sukori]

Current:

• minishell_loop initializes core
• exec assumes that the first argument is a built-in command (ls, cd, pwd,...) from envp
• error in any other situation
• one function for mono command and one other function for pipes

Expectation:

• [x] minishell_loop initializes core
• [x] exec tries to access(core->init->params[0], X_OK)
  • [x] on success, this was an executable file
• [x] on failure, this is probably a /bin/... -> try on envp
• [x] the loop function for pipes also works with 0 pipes -> replace execute()
• [x] infile
• [x] outfile
• [x] error in any other situation
• [x] error does not crash
• [x] detect builtins
• [x] signals

So far, bugs seem properly handled
