1.2.0

Fixes:

• typings in tasks page and repositories
• limit length of the Result column to avoid row height breakings

Updates:

• add new type of task state - "abandoned"
• renamed state: "pending" -> "running" for more clarity
• add indexes on "state" and "execution_time"
• add a nitrojs hook which runs on close event and marks all "running" tasks as "abandoned"
