Panic because the settings

Panic when matching theme
The json files are not existed in C:\Users\Administrator\AppData\Roaming\Vadoola\Tomotroid\config\. So settings::load_settings(); get a default setting, which "theme" is "Pomotroid", while the default theme is named "Rangitoto".
I solved it by change default theme to "Rangitoto".

Panic when save settings
Because the folder C:\Users\Administrator\AppData\Roaming\Vadoola\Tomotroid\config\ is not exised. Must check the folder before saving.
