Make LLTransUtil::parseStrings() merge all relevant strings.xml files.
Until now, adding a xui/en/strings.xml file in any non-default skin meant you
had to clone the entire file, editing only the particular entries you wanted
to override. With this change, we load strings.xml file(s) from the default
skin before loading the specified skin -- so a non-default skin can now
provide a strings.xml file containing only the specific entries it wants to

Tip: Filter by directory path e.g. /media app.js to search for public/media/app.js.
Tip: Use camelCasing e.g. ProjME to search for
Tip: Filter by extension type e.g. /repo .js to search for all .js files in the /repo directory.
Tip: Separate your search with spaces e.g. /ssh pom.xml to search for src/ssh/pom.xml.
Tip: Use ↑ and ↓ arrow keys to navigate and return to view the file.
Tip: You can also navigate files with Ctrl+j (next) and Ctrl+k (previous) and view the file with Ctrl+o.
Tip: You can also navigate files with Alt+j (next) and Alt+k (previous) and view the file with Alt+o.
