2.1.5.5

• Issue 1647 - Added limited support for SAQL files (those with the .saql file extension) including syntax highlighting, simple code completion, simple auto-indentation, quote/paren/brace/bracket matching. This is not intended to be full custom language support but rather to provide improved authoring of SAQL files from within the IDE.
• Issue 1784 - Allowed remote action methods to be picked up from the class hierarchy and not the leaf class through which the reference is established.
• Fixed an Apex code completion issue in assignment expressions used as invocation arguments in constructors/new expressions.
• Denoted the SFDX cache configuration file as per-instance/private so that it cannot be exported/imported and is not included when syncing with a settings repository.
• Other related fixes and improvements.
