Generalized 'No such file or directory handling'

[kittaakos]

• Removed the .h literally match from the regexp.
• Let the submatch handle the .h suffix.

To handle both types of error messages:

• Alma.h: No such file or directory and
• chrono: No such file or directory.

---

Examples:

#include "Alma.h"
void setup() { }
void loop() { }

#include <chrono>
void setup() { }
void loop() { }

Closes #30.
