convert UTF-8-BOM to UTF-8.py.ps1

# ============================================================
#  Converteste fisiere HTML din orice encoding cu BOM -> UTF-8
#  Ruleaza din PowerShell:
#    .\convert-to-utf8.ps1
#  sau cu alt folder:
#    .\convert-to-utf8.ps1 -Folder "e:\Carte\BB\17 - Site Leadership\Principal\ro"
#  sau recursiv (subfoldere):
#    .\convert-to-utf8.ps1 -Recurse
