Note: according to cppreference it is necessary to convert char to unsigned char when using std::tolower and std::toupper, otherwise the behaviour would be undefined.
This allows LLE library applets (like swkbd) to properly close and return to the application instead of hanging.
There is still a bug in our rasterizer cache that may cause crashes some time after an applet is closed, but that is tangential to this change and should be tackled separately.
Currently LLE applets cannot exit properly in Citra and causes Citra to hang. We are already providing HLE for applets, and the LLE applets are preventing users who dumped their system files from using the applets correctly. Before the further fix is done, I think we should temporaily disable loading LLE applets.
When you change the language when a game is running, the "Continue" action in the "Emulation" menu would become "Start". This commit fixes the issue by checking and setting it if it should be "Continue". It seems that this is the only place with this issue.
Previously, once you change language, the texts in the buttons in the Input tab will disappear. It is because the default text in the buttons are empty, and we did not update the text after translations are reloaded, aka texts are reset. This commit fixed the issue.
Due to a bug of Qt Linguist, the spliters in numbers cannot be parsed correctly and will cause strange issues. As far as I know, this caused 4 texts to be untranslated (translation source for them are not generated). Before the Qt bug is fixed (and we move to that version), I think we can temporarily remove the spliters from the numbers.
Previously for installed titles, the file type would be NCCH (assumed as CXI) and the extension would be ".app". This would trigger a warning of the file "having a different type than its extension", which is actually not true here.
This doesn't depend on class state at all, so this can be made internal.
While we're at it, amend the function to take its arguments by const reference.
QString initializes to an empty string by default, so this does nothing
meaningful. While we're at it, use a constructor initializer list for
initializing the gamelist member variable.
These operators don't modify internal class state, so they can be made
const member functions. While we're at it, drop the unnecessary inline
keywords. Member functions that are defined in the class declaration are
already inline by default.
