Update console and in-game weather commands to `weather <clear|rain|thunder> [duration in seconds] [WorldName]` and `toggle downfall [WorldName]` to match vanilla options and the updated `time` command parameter ordering as discussed in mc-server/Core#97. Merged weather console command code with in-game command code. Moved local `GetWorld()` and `GetConsoleWorld()` functions from time.lua to functions.lua, merged them, and made then global functions. Added `toggledownfall` console command to Info.lua and updated `weather` console command handler. Added notes to tps.lua to alert future coders to usage outside of the file.
Update Info.lua file, added comment to weather.lua
Updated README.md and Info.lua
Corrected ParameterCombinations in Info.lua
Add missing newline at end of file
Fixed comments, grammar
Changed TPS to a constant 20

Initial Reorganization/Reimplentation of `give` and `item`

Merge pull request #109 from jonfabe/WebadminWorldsFix

Fixes world manipulation through webadmin.
Improved handing of data tag strings

Now can handle `:`, `[`, `]` in quoted strings. Cannot handle `]` in unquoted strings - this differs slightly from vanilla which can handle it as long as it has a matching `[` before it.
Added missing new line
Implemented basic error detection
