One based indexing is enabled by default. * Updating js lists to do zero and one based index Updated generated JavaScript to change depending on whether one based indexing is enabled or not. * Updating js text to do zero and one based index Change so that JavaScript generated for text blocks either assumes blocks use zero or one based index based on setting. * Start of python indexing Start of work on allowing one and zero indexing for generated python for lists. * Fixing bug and lint fixed Fixing bug caused by not setting the return of concat when concatenating lines for sublist and substring functions. Also renamed these functions to be getSubsequece. Fixed lint errors with spacing * Converting from if to switch statements Comverting if statements to switch statements when appropriate and adding spacing. * Modified sublist JavaScript generation Added case so that helper function is not generated if not necessary. Helper function is not generated if list length is not needed or if list is a simple block (such as a variable, as oppossed to a function call or list create). * Stripping unecessary ids Removing ids from xml file. * Localisation updates from https://translatewiki.net. * Fix typo in flyout.js (#403) * Fix typo in flyout.js (#402) * Localisation updates from https://translatewiki.net. * Add indexing setting for JavaScript Generation Adding setting to allow for switching between zero and one based indexing for Blockly Blocks such that the generated code will use this flag to determine whether one based or zero based indexing should be used.

Renaming variables to make functions more readble. * Fixing sublist order and sort variable Fixing order used for valueToCode for sublist and renaming list variable in sort to match rest of code.. * Fixing order constant order Removing operator () that was incorrect and addiung ~, * Fixing order and indentation Fixing order return fro create lists blocks and fixing indentationn for string array. * Fixing order and renaming variables Fixing order to be the correct strength and renaming variables to be more readable/ * Changing assert blocks for unit tests Changing assert blocks to have a value input instead of a field so there is more flexibility in writing tests. * Cleaning up and adding missing order tests Adding tests for order for paramters for list blocks that weren't being tested to uncover bugs. Test were also cleaned up/reorganized/renamed to be more readable and shorter vertically (but lines wider horizontally). * Compile error fix and order in Dart generation. Fixing compile error in generated code and incorrect order in get sublist for Dart. * Fixing typo in getIndex and invalid parameter name Fixing type in getIndex where list code should have been appended but instead an undefined variable was added.
