Matt Borgerson 9c06980275 ui: Redesign user interface 
Introduces a new user interface that looks much nicer, is easier to
navigate with controllers, provides more context to users, and is
scalable. Some additional features are included.

* Adds 'popup menu' with actions that can be used easily from controller
* Adds 'main menu', unifying other configuration dialogs
* Adds port-forwarding user interface
* Adds screenshot feature
* Adds volume control feature
* Adds gamepad auto-bind option
* Adds vsync configuration option
* Adds auto UI scaling
* Adds preferred window size selection
* Adds AV pack selection
* Exposes some existing config items in GUI

/* A portable library to create open and save dialogs on linux, osx and
* windows.
*
* The library define a single function : noc_file_dialog_open.
* With three different implementations.
*
* Usage:
*
* The library does not automatically select the implementation, you need to
* define one of those macros before including this file:
*
* NOC_FILE_DIALOG_GTK
* NOC_FILE_DIALOG_WIN32
* NOC_FILE_DIALOG_OSX

NOC_FILE_DIALOG_OVERWRITE_CONFIRMATION = 1 << 3,

// There is a single function defined.
/* flags : union of the NOC_FILE_DIALOG_XXX masks.
* filters : a list of strings separated by '\0' of the form:
* "name1 reg1 name2 reg2 ..."
* The last value is followed by two '\0'. For example,
* to filter png and jpeg files, you can use:
* "png\0*.png\0jpeg\0*.jpeg\0"
* You can also separate patterns with ';':
* "jpeg\0*.jpg;*.jpeg\0"
* Set to NULL for no filter.
* default_path : the default file to use or NULL.
* default_name : the default file name to use or NULL.
*
* The function return a C string. There is no need to free it, as it is
* managed by the library. The string is valid until the next call to
* no_dialog_open. If the user canceled, the return value is NULL.
