AppCompatImageButton ignores "tint" theme attribute on API 19, therefore, they had to be specified directly, these attributes can be removed after the KitKat support is dropped.
It will be shown even when nothing could be loaded not due to a network error, and the user can choose to ignore or report it.
Also improve error reporting arguments
Also completely refactor error activity
Also improve some code here and there
