Modules cleanup

[adamgall]

Did a lot here, in an attempt to clean up our new "Modules"

• Totally just removed the DecentHats_0_1_0 contract. Oh well. I guess I'm coming around to the fact that there's really no real need to keep a hold on this thing. It's not "installed" on any Safe permanently. So anyway, yeah, it has been superseded by the DecentHatsCreationModule.
  • This also allowed me to get rid of that half-baked IHats interface.
  • This also allowed me to remove the full subdirectory in those hats and sablier interface directories.
    • This is going to force a redeployment of the DecentSablierStreamManagement contract, but I'm ok with that.
      • So while we're at it, I've also renamed this contract to DecentSablierStreamManagementModule
• Moved all of the new "Modules" into a "modules" directory.
• Tightened and cleaned up the structs used in our three-contract HatsModule contracts (Create, Modify, and Utils)
  • Modified the input params to the Create contract to support multiple Hats/Roles at once
  • Created a standalone struct for these input params
    • Now the implementation of DecentHatsModificationModule is super clean
• Renamed DecentHatsUtils to DecentHatsModuleUtils for naming consistency.
• Reordered some deployment scripts
• Removed deployment artifacts for DecentHats_0_1_0 and DecentSablierStreamManagement contracts on all networks
• Beefed up the MockHatsElectionEligibility contract to more accurately mimic the real thing.
• Fix a bug in DecentAutonomousAdmin
  • Via more accurate tests.
• Fixed all the mocks, tests, etc

Hmm, I'm also thinking that I should think more critically about the pragma solidity version numbers in the new modules files...
