Remove all instances of unwrap() from config

Unwrapping inside the config file parsing can lead to some issues that
prevent us from falling back to a default configuration file.

One instance of that issue was mentioned in #1135.

Now all instances of `unwrap()` have been removed and replaced with
proper error handling. This will make the config more robust and
prevents live reload from silently breaking while alacritty is running.

This also fixes a few currently existing clippy issues.
Clippy added an additonal lint which complains about `MyStruct { field:
field }`.

These issues have been fixed, except for some false-positives and issues
in external macros which will probably be fixed with future updates (rust-lang-nursery/bitflags#149)
