Switch Theme Injector v4.4 und NXThemes Installer v2.3

* Added a button to easily extract nxthemes
* Dropped the included DDS converter for better linux compatibility
* * This means that now only JPG and DDS images are supported for backgrounds and only PNG and DDS for custom applet icons.
* * PNG isn't supported for backgrounds as having a lossless image only increases the theme size as eventually it gets compressed with DXT1 (lossy !), for best quality use a good DDS encoder
* SZS Patcher tab is now hidden by default, you can enable it from the advanced settings if you need to.

* Firmware 10.0 support
* Shiny new UI for the theme installer
* * Includes several bug fixes, no more seizure-inducing flashing text when navigating or installing multiple themes !
* Support for font color in the nxtheme format
