Convert classic figure scripts

[LinqLover]

• convert classic figure scripts (%%) to modern \ExecuteSmalltalkScripts (2ef83d1)

  This did it:

  | matcher files |
  matcher := '%%\{(SBESqueakPicture)(([^\r\n]*([\r\n]|\r\n))%%)*(])\}' asRegex.
  files := SBEScriptBuilder getTexFilesIn: SBEScriptBuilder resourceDirectory.
  files
  	collect: [:file | file -> (SBEScriptBuilder collectScriptsFromFile: file)]
  	as: Dictionary.
  files do: [:file |
  	file writeStreamDo: [:stream | | translated |
  		translated := matcher copy: file contents translatingMatchesUsing: [:s | '\begin{ExecuteSmalltalkScript}' , (matcher subexpression: 5) , (((matcher subexpressions: 2) , (matcher subexpressions: 4) , (matcher subexpressions: 6)) join) , (matcher subexpression: 5) , '\end{ExecuteSmalltalkScript}'].
  		stream reset; nextPutAll: translated]]

• Migrate all senders of SBESqueakPicture to SBEScreenshotRecorder (716c259)

  Regex:

  SBESqueakPicture( writeTo: .* (frame: .* ))using:(?= \[)
