Allows to set the string value of a key. Perists the value to the
configuration file.

Introduces a small state machine which parses the file character by
character. This eases the logic around parsing whole lines
significantly.

Now also trims lines, handling all non printable characters correctly.

As opposed to defining all possible keys at compile time.

In preparation for next commit

Mostly changing things like if { ... return} else { ... } to not have
an extra indentation level of the else part.

The diff is probably very weird even with stripped whitespace.

Adds simple config parser along with config_ API that:

- allows typed querying of config values
- types supported: boolean, integer, floating point and string

unknown options are ignored and LOG_WARNed on the console
