Done.

Standard resources are embedded into executable by default.

When your application uses custom resources, you can embed 
resources into executable and/or specify external resource 
directory(s).

To embed resources, put them into views/res directory, and create 
file views/resources.list with list of all files to embed.

Use following code to embed resources:

----
/// entry point for dlangui based application
extern (C) int UIAppMain(string[] args) {

     // embed non-standard resources listed in 
views/resources.list into executable
     
embeddedResourceList.addResources(embedResourcesFromList!("resources.list")());

     ...
----

Resource list resources.list file may look similar to following:

----
res/i18n/en.ini
res/i18n/ru.ini
res/mdpi/cr3_logo.png
res/mdpi/document-open.png
res/mdpi/document-properties.png
res/mdpi/document-save.png
res/mdpi/edit-copy.png
res/mdpi/edit-paste.png
res/mdpi/edit-undo.png
res/mdpi/tx_fabric.jpg
res/theme_custom1.xml
----

As well you can specify list of external directories to get 
resources from.

----

/// entry point for dlangui based application
extern (C) int UIAppMain(string[] args) {
     // resource directory search paths
     string[] resourceDirs = [
         appendPath(exePath, "../../../res/"),   // for Visual D 
and DUB builds
         appendPath(exePath, "../../../res/mdpi/"),   // for 
Visual D and DUB builds
         appendPath(exePath, "../../../../res/"),// for Mono-D 
builds
         appendPath(exePath, "../../../../res/mdpi/"),// for 
Mono-D builds
         appendPath(exePath, "res/"), // when res dir is located 
at the same directory as executable
         appendPath(exePath, "../res/"), // when res dir is 
located at project directory
         appendPath(exePath, "../../res/"), // when res dir is 
located at the same directory as executable
         appendPath(exePath, "res/mdpi/"), // when res dir is 
located at the same directory as executable
         appendPath(exePath, "../res/mdpi/"), // when res dir is 
located at project directory
         appendPath(exePath, "../../res/mdpi/") // when res dir is 
located at the same directory as executable
     ];
     // setup resource directories - will use only existing 
directories
     Platform.instance.resourceDirs = resourceDirs;

----

When same file exists in both embedded and external resources, 
one from external resource directory will be used - it's useful 
for developing
and testing of resources.

As well, it's no more required to set theme and language in 
UIAppMain if you don't want to change default values.
