    [NOTEPAD] Make "UTF-8 without BOM" default (#5081)
    
    - Define a constant ENCODING_DEFAULT that is equal to ENCODING_UTF8.
    - Initialize Globals.encFile as ENCODING_DEFAULT.
    - Reset encoding and line ending in DIALOG_FileNew.
    - AnalyzeEncoding returns ENCODING_DEFAULT for non-zero ASCII text.
    - Remove unnecessary DIALOG_StatusBarAlignParts calls.
