#1532 In-memory file viewer

[Reese]

Small but useful improvement for "7-Zip File Manager"

I suggest adding a new option to file dialog that will allow users to view text files without creating temporary files (in-memory). Currently "View" option from context menu extracts the file to a temporary folder and opens this file using "Notepad". This could be modified to support in-memory loading. So essentially 7-zip will need to uncompress (+? decrypt) selected file inside the buffer instead of a temporary file. Then this buffer could be passed to created "Notepad" process using WM_SETTEXT message. Alternatively more complicated approach could be used by adding in-app viewer.

This will be useful for viewing small text files without creating temporary files on the disk (specially for SSDs). Also might be useful from security and performance point of view.

It shouldn't be hard to implement assuming that 7-Zip already supports in-memory operations for extracting & decrypting. Perhaps some flags for CreateFile could be used to achieve this behavior without drastically changing existing flow (like FILE_ATTRIBUTE_TEMPORARY combined with other options).
