[FEATURE REQUEST] Expanding trimming feature

[the-liquid-metal]

1. At the moment, Trim text only accept single string. We need several rule rows just for trimming several string. The more rows we have, the more effort we have to put into maintaining them.
   Suggestion: refactor Trim text field to becomes textarea and accept multiline of multistring.

2. Sometimes we are faced with a combination of strings that need to be trimmed. For example, some filenames start with "lorem ipsum", and others start with "lorem", "ipsum", or "ipsum lorem". All of these must be trimmed. Populating all combination and put all of them into Trim text field is not convenient. Alternative ways are (all of these are also not convenient):

   • create multiple identical trimming text rules containing only particle strings.
   • use replacement text rule with the risk of erasing text in the middle of filename.
   • use regex rule with complex pattern.

Suggestion: add Method field with options:
- Single iteration. This option is for users who are sure that all filenames are simple.
- Iterate until clean.
