mostly cosmetic and very small changes

[EnthusiastNT]

• • added a check on isset($table[0]) because that threw an error once
• • utf8mb4 instead of utf8 as default as recommended in the docs
• • mb_substr instead of substr since we use utf8
• • added 3 function aliases for easier understanding (see CHANGED)
• • corrected some spelling and grammar in comments
• • removed a few "@throws Exception" where it wasn't throwing anything
• • added some line breaks for consistency
• • moved orWhere() after where() because... OCD I guess

@EnthusiastNT great cleanup thank you. Can you please remove all the noise comments like CHANGED, remove a changelog on top and as well remove new introdouced helper functions? I dont see much use of this functions since they are acting as 'sugar for the sugar'. I will be happy to merge this in after. Thank you again
