based on work of Florian Jenett

- included ANTLR 4.5, building PDE and running sketches works
- error reporting is not yet implemented
- parses size() and adds sketchXxxx methods

- moved tests to java mode folder
- fixed expected whitespace in tests
- added sketchXxxx methods to expected test outputs
- error reporting tests are disabled, other tests are gree

…ocessing into JakubValtar-feature-antlr-4.5

Migrate the Java 8 antlr file.

Some style clean up, added error msg handling, and a switch to using ANTLR for all preprocessing within the PreprocessingService.

Refactor for the ANTLR visitor for code quality and test.

Added specific funcationality for localization for syntax error and have included text for English and Spanish.

In response to @monkstone feedback, removing the line checking for compilation failure in ParserTests. While ensuring that compilation fails when expected is useful, the line parsing is unhelpful since JavaBuild and PreprocessingService use the JDT. This only makes the test brittle due to regex over stderr.

Allow the preprocessor to emit ImportStatements, allowing the JDT to read extra libraries (including contributed ones) at compilation time.

Allow preprocessor to emit ImportStatements, fixing contrib libs.

Minor stylistic cleanup in issue message simplifier as well as a fix with line attribution for missing name / type.

Updated processing of size to be consistent with current processing and added additional methods to the "special" methods list requiring visibility modification. In response to @monkstone. Thanks @monkstone!

Fixed special methods processing in antlr traversal.

For consistency with prior processing, disallow use of the default visbility and instead prepend public modifier if no modifier is given. In response to @dzaima.

Sync #37 into ANTLR

In response to @dzaima, fix IDE import errors by passing all imports into the JDT even if they are listed in code as result of preprocessor.

In response to @dzaima feedback, added support for inserting public into method with non-visiblity modifiers (previously undefined behavior) and added support for full screen. Related to processing#5753 but part of #15.

Antlr various fixes

There were some issues related to public modifier injection that were introduced by #37, causing a large number of sketches to fail. This impacts #15 and does not impact but is related to processing#5753. To prevent regressions, also introduces JDT based tests to ensure edits are valid.

[antlr branch] Fix issues related to #37.

Fix automated code folder imports.
