OrganizeImports v0.5.0-alpha.1

This pre-release contains a new feature and a couple of backward-incompatible changes. It aims to make existing IntelliJ IDEA users' life easier when adopting OrganizeImports.

• Allow customizing blank lines between organized import groups (#142)

  The IntelliJ Scala import optimizer not only allows you group imports but also allows you to decide whether a blank line should be inserted between two adjacent import groups. This feature introduces a new configuration option blankLines. When it's set to Manual, you may configure blank lines by adding "---" to the groups option. For example, now you can have the following configuration to group java, javax, and scala imports together without blank lines:

  OrganizeImports {
    blankLines = Manual
    groups = [
      "*"
      "---"
      "re:(javax?|scala)\\."
    ]
  }
  

  By default, blankLines is set to Auto, which preserves the original behavior, i.e., a blank line is automatically inserted between adjacent import groups.

  This makes migrating IntelliJ Scala import optimizer configurations of existing projects to OrganizeImports easier.

• Default value changes (#143 and #146 by @sideeffffect)

  • groupedImports now defaults to Merge
  • groups now defaults to ["*", "re:(javax?|scala)\\."]

  Both values follow the default configuration of the IntelliJ Scala import optimizer (as in version 2020.3).

Many thanks to all the feedback and contributions!
