Merge pull request #13 from cheptsov/master

A bugfix for not closing script tag
Ability to generate [yet?] missing attributes like onclick.

Added info about issue tracking
Add "umbrella" module so there is no orphan folders like 'license'
Add square brackets syntax for accessing tag attributes
Kara-9: re-layout. Prepare for binary distribution
Build binary distribution
Build artifacts manually (to lessen depend on IDEA build)
