Text trim whitespaces

Block is used for removing spaces around source string.

Removing modes:

• both sides: remove spaces from both sides of the string,
• left side: remove spaces from left side of the string,
• right side: remove spaces from right side of the string.

Right part defines source string and argument is required. Output of the block is a string value with removed spaces.

In case supplied string variable is not actually string returns None.
