If the user has both Electrum and Electrum-LTC installed, and they have the environment variable ELECTRUMDIR set (e.g. to ~/.local/share/electrum), then Electrum-LTC will place its user files in the same directory as Electrum, which can result in one program's config overwriting the other, as well as servers and wallets getting mixed together.
So this PR changes the name of the user directory environment variable to ELECTRUMLTC_DIR to avoid that confusion.
