Avoid performing non trivial operations on files

[facchinm]

Fixes #7843 as per @cmaglie comment.

Translations should be updated removing the second part of the information text.

RATIONALE:

• The IDE used to ask the user if s/he wanted to move a file inside the folder with the same name (on double click, for example)
• This approach only works for single file sketches; for anything more complicated, the file would be moved but not the whole project (causing compile failures)
• Moving a sketch to another folder should move all files #6404 tried to fix this by moving ALL the files inside a folder with the same name (works if you downloaded a project from github as ProjectName-master)

Problem: most of the times .ino files downloads from the web are being saved in the Download folder, so the move operation copied the whole Downloads content into that folder 😳

@cmaglie suggested the IDE shouldn't be allowed to do this kind of operations; this patch removes the automatic move and requires the user to create the folder and move .ino file inside it manually

Uhm, I'm a bit confused:

• This talks about fixing Moving a sketch to another folder should move all files #6404, which is a PR, not an issue?
• This talks about a comment by Cristian, but I see no such comment in Moving a sketch to another folder should move all files #6404 (or Weird errors when sketch name and directory name differ in capitalization only... #6402, which is the underlying issue).
• Your comment message talks about "avoid non-trivial operations", which suggests to me that the commit removes multiple operations in multiple places, and the messae does not tell me what it does instead. Would it not be better to be more explicit and say "Do not offer to rename a sketch folder when it is named wrongly" or something like that? Also, I'm missing rationale for this change, which IMHO should be in the commit message, not in a vague reference to an issue (which might become unfindable at some point, or even be wrong fro mthe start...)

Argh, I was a bit in a hurry and pasted the wrong link...
I'm also expanding the rationale, just to make explicit where and why the change should be applied.
Thanks for checking anyway 😉
