Add functions for accessing the current session log file to XT
Rename EnableProfileMenu to DisableMenusWhileStreaming

Move OpenLogFolder menu item to help menu

Leaving the localization strings unchanged for now for less confusion
on the translation site
Increase profile limit to 1000 and move magic constant to OBS.h
Add log file uploader implementation with GitHub Gist as upload target

As always, translation strings are open for discussion
Add UI for log file uploader

Also includes UI for opening specific log files directly from the OBS UI

On successful upload the resulting (non-API) URL is copied into the
clipboard and a message box signalling successful upload is displayed.
This should probably be expanded into a dialog with buttons to retry
copying the URL to the clipboard and maybe a text box with the URL
preselected.

Whether or not the upload URL should be cached (per log file) and reused
in case of duplicate upload (attempts) is still open for debate.
Fix Json escaping of quotes

Order is important for multipass escaping
Make sure we're throwing to log ugly stats stuff (division by zero case)

Also add missing include ...
Add OSMonitorDirectoryCallback helpers

The callback is executed whenever a file is created/deleted/renamed
Monitor log file directory and refresh log upload menu if necessary

No new log files will be added to prevent the current log file from
becoming the topmost entry, which would render the "Upload last Log File"
entry useless
Fix log upload menu in case all previous log files are deleted
