Move all static inline styles to stylesheets

[emmoistner]

I'm lazy... 😞

A lot of initial static styles weren't placed in stylesheets. All that aren't defined by config or runtime should be migrated to stylesheets.

Example

// BEFORE
<View style={{ height: 25, width: 35 }} />


// AFTER
<View style={styles.container} />

// later in the file

const styles = StyleSheet.create({
  container: {
    height: 25, 
    width: 35
  }
})
