Fix session.xml description throughout.

- Correct misinformation (the other-config-files section incorrectly said it was always in the installation directory)
- Clarify its confusing nature (since it ignores the cloud setting, but follows the per-user rules otherwise)

 ## Configuration Files Location
 
-In a standard installation, the per-user configuration files go in `%AppData%\Notepad++\`. (For a refresher course on `%AppData%`, see the [Community Forum FAQ's `%AppData%` entry](https://community.notepad-plus-plus.org/topic/15740/faq-desk-what-is-appdata).)  The machine-wide configuration files go in the executable directory (so usually `c:\program files\notepad++\`). When Notepad++ is looking for [shortcuts](#keyboard-shortcuts-shortcuts-xml), [stylers and themes](#highlighting-schemes-stylers-xml), [function list](#function-list) definitions, and [user defined language](#other-configuration-files:~:text=Configuration%20location%20for%20the%20User%20Defined%20Languages%20feature) definitions, it will try to read from the per-user directory; if the right file isn't found there, then it will check machine-wide configuration files.

 In a portable installation, the configuration files all go in the same directory as the `notepad++.exe` executable (or the appropriate subdirectory), and there is no per-user configuration location. (An installation is treated as "portable" if the zero-byte `doLocalConf.xml` file is present alongside the `notepad++.exe` executable. The **?** menu's **Debug Info** will show `Local mode: ON` for a portable version.)
 
-If you enable the [Cloud settings](../preferences/#cloud), some per-user configuration files will go in the defined directory (including `contextMenu.xml`, `shortcuts.xml`, `userDefineLang.xml`, `langs.xml`, `stylers.xml`, and `config.xml`; the `userDefineLang\` subfolder can be placed there as well, though it won't be created by default when the Cloud settings folder is first populated).

It should be emphasized that `session.xml` does _not_ work in the cloud folder, so if you have the cloud settings, `session.xml` will still be found in either the `%AppData%` hierarchy for a normal installation, or in the installed directory for a portable installation.  
 
-There is a [command-line option](../command-prompt/) `-settingsDir` which will set a new directory for the per-user configuration file location.
+There is a [command-line option](../command-prompt/) `-settingsDir` which will set a new directory for the per-user configuration file location.  (Unlike the cloud directory, `session.xml` does work in the `-settingsDir` directory, so if you want to have all your per-user configuration, including your session information, in your cloud folder, it might be wise to not use the Cloud settings option, and instead point `-settingsDir` to the cloud folder.)
 
 **Search order**: If the `-settingsDir` option is set, that configuration file directory will take priority over any other configuration file directory. If the Cloud directory setting is defined and enabled, that will take priority over the portable or standard configuration file directory. If `doLocalConf.xml` is present, the portable configuration file location will take priority over the `%AppData%\Notepad++\` directory. If none of the other configuration file directories are active, then the standard configuration file directory is `%AppData%\Notepad++\`. If it cannot find a configuration file in any of the per-user locations, it will use the version from the same directory as the executable.
