2.3.0 release came with a lot of bugs, so we're short-cycling the 2.3.1 release to get a large number of bugfixes out. There are also a few feature changes, see the full changelog below:

NETSCRIPT:

* Added ns.setTitle, which sets the titlebar of a script's tail window (@d0sboots)
* Added ns.getFunctionRamCost, which gets the ramcost of a netscript function (@G4mingJon4s)
* ns.ls results will filter as if the filenames have a leading slash (@Snarling)

GENERAL / MISC:

* Changed tail window buttons into icon buttons, allow setting custom title, and tail window bugfixes. (@d0sboots)
* Terminal no longer scrolls to the bottom constantly while an action is being performed (@bezrodnov)
* Added a close button to modals (@bezrodnov)
* Fixed several issues with script editor tabs (@bezrodnov)
* scp terminal command can copy multiple files at once, like help text indicates (@Snarling)
* Root directory is no longer displayed as ~ in the terminal prompt, it is displayed as / (@Snarling)
* cd with no arguments will change to the root directory (@Snarling)
* Documentation updates (various)

HOTFIXES (these were already backported to 2.3.0 before 2.3.1 release):

* Several important fixes for savegame migration issues from older version (@d0sboots)
* Prevent scripts from loading during intial migration to 2.3.0 save format, to prevent a crash that could occur. (@Snarling)
* Fix scp logging (hostname was being logged incorrectly in multiple places and showing as [Object object]) (@Snarling)
* Update terminal parsing logic so that the old syntax for alias works again. (@Snarling)
* Fix clickable script links from ls command not working outside root directory (@Snarling)
* Fix an issue with Find All Valid Math Expressions not accepting empty array when that was the solution. (@Snarling)
