Initial support for @CustomLog

[juriad]

Since support for @CustomLog (see projectlombok/lombok#2086) will be present in the next release of Lombok, I also added it into this Intellij plugin.

I have tested it briefly, however I have a couple of questions:

• Performance.
  The declaration is a quite complicated expression that requires parsing which can potentially be costly. How often are methods validate and generatePsiElements called?
  If there would be a performance problem, we could introduce caching of parsed declaration, but again I don't know if we need to deal with multithreading or even what the cache key should be as the configuration value is found for a psiClass while lombok.config is only one per module.

• Tests
  I couldn't find a way how to unit test the implementation as we need to set lombok.config before the test is performed. Lombok itself allows to define a special comment which sets the configuration. https://github.com/rzwitserloot/lombok/pull/2086/files#diff-336a74e0014249db8ef0ef331af898f8R1 Do we have something similar here?

• License
  Shall I add myself to a list of contributors, or sign something in blood?

Is there anything that catches your eye, that I should change?

Thank you very much for your work! I'm just returned from vacation and will look on your code next days.
Please add yourself to the contributor list in readme.md file in the meanwhile:-)

For tests you can look on "lombok-intellij-plugin/testData/configsystem/..."
I think we can use it for this too.

[mplushnikov]

@juriad are you planning to update your PR?

[juriad]

@mplushnikov Yes, I intend to continue. I finally got some time allocated for this.

[juriad]

@mplushnikov I pushed a new version which fixes all problems. I also had to adjust the grammar in lombokConfig.flex which I hope is correct.
