Description:

This adds !votedifficulty commands that allow you to start F1/F2 vote (thanks to NativeVotes)
(I have actually seen that too many players don't understand the sourcemod menu votes, especially in l4d2)

Usage: !votedifficulty <difficulty> (easy;normal;hard;impossible)

Requirements:
NativeVotes
[L4D2] Difficulty Override because l4d2 doesn't listen to z_difficulty cvar in gamemodes other than coop ( and this one requires the left4downtown2)

Changelog:

• 28.01.2018 - Plugin created
• 29.01.2018 - Now the command cannot be used from the server console,
  - only survivors can use the command now ( I decided so because the difficulty command has the most impact on the survivor team, infected shouldn't force change how difficult the game is if there are more infected than survivors, but they are counted in the vote)
• 30.01.2018 - Ren89 uploaded edited version with translation file ( Thanks )
  * vote time now respects the sv_vote_timer_duration cvar
  * cannot start another vote until the first one finishes

Nice!
Good example how to use NativeVotes for custom votes.
a little changed - some checks and translations
but I'm not sure about l4d2 gamemods/mutations, where standart diff vote exists

Thanks , it is my first plugin and I don't know much about the translations yet and I could also add additional arguments so the "advanced" and "expert" trigger the vote too but I didn't find it that much important for now.
I will add your version to the original post if you have no problem with that
