Quick bugfix.

Actually works on php5.3 now!!!

Restore PHP5.3 compatibility

Minor optimizations

Lots of stuff.

* cli view and simple html share same-ish colors
* cli view shows color indicators of current level
* plain view readability enhancements
* datetime of dump in rich view
* phpstorm-plugin renamed to phpstorm-remote, doesn't work either way, thanks, jetbrains
* improvements to enum and alternatives displays
* switched functionalities of ! and + modifiers as it makes more intuitive sense
* improvements to classname, color, splfileinfo variables
* finally fixed footer [+] keyboard navigation
* TAB button now jumps out of sage keyboard navigation
* removed more useless tests, sigh this needs work
* more obvious indication that direct, non-variable parameters were passed
* streamlined output simplification, just makes sense now

Known issues:
since PHP8.2 the debug_backtrace output changed what line is indicated, effectively breaking current variable name detection for multiline sage calls, not too difficult to fix.

New features: `print s()`, `s(2)`, many QOL improvements

 * `Sage::$outputFile` to write to instead of echo
 * `print sage();` modifier as shorthand for the above to write to `sage.html` in __DIR__
 * `sage(2)` shortcut to print just the files of the backtrace
 * `sage()` now prints the same info as `microtime()`
 * Documentation and visual improvements

Add d() shorthand to support drop-in replacing Kint

Replaced default IDE link provider. Still PHPStorm, just another means.

* The good old remote call plugin was replaced by IDE remote control.
* The new plugin is not as liberal for what the file path is prefixed, so improved app-root detection, removing Sage::$appRootDirs in the process. Breaking change but no one used it, fact :)
* Updated fonts to be a more modern selection. Bolder, nicer, readabler :)
* Random inspections fixed

Maintenance release.
