String: removing implicit numeric conversions and new approach to "if (s)".
...
This makes explicit the String constructors that take numeric types and chars and removes the versions of concat() and operator=() and operator+() that accept numberic types.
It also replaces the operator bool() with a operator that converts to a function pointer. This allows for uses like "if (s)" but not "s + 123". See: http://www.artima.com/cppsource/safebool.html . This allowed removing the disambiguating operator+() functions and relying solely on StringSumHelper and anonymous temporaries once again.
Also, now treating unsigned char's like int when constructing Strings from them, i.e. String(byte(65)) is now "65" not "A". This is consistent with the new behavior of Serial.print(byte).

Adding additional String + operators for disambiguation.
...
The operator bool() means that you could implicitly convert a String to a bool and then add it to it an int, for example. Which means our operator+ has to match exactly or it will be ambiguous.

Modifying String.concat() to return success or failure, not this.

Which means you can't chain multiple concat() calls together, but you can check if they succeeded or not.

Don't return the string when modifying its value.
...
Changing toLowerCase(), toUpperCase(), trim() and replace() to return void instead of a reference to the string that's just been changed. That way, it's clear that the functions modify the string they've been called on.

Removing F("string") syntax for now.

We should probably add something like this back in later, but I want to do one thing at a time. This removes the __FlashStringHelper class as well.

Changing String::toCharArray() and getBytes() to accept a buffer, rather than return one. That way they don't expose the internal representation of the String class, allowing future optimization. Thanks to Paul Stoffregen.
