Cinch's Missing Blocks

Changes:

• Updated Polish translation with new blocks (Thanks to Piotrus983)
• Introduced a potential fix for a rare crash on servers
• Fixed typos in the sulfur block translations
• Added translators to contributors in mod menu

Known Issues:

• Brazillian Portuguese translation is not updated with new blocks
• The snow brick wall accepts pickaxes as well as shovels as the correct item. (Weird hardcoded issue with tags that only causes a slight inconsistency that 99.9% of players won't notice)
