0.2.5

Congratulations about Julia 1.0! We have some compatibility issues with this plugin and Julia 1.0,

and they're mostly fixed in this build.

Also, we've introduced some awesome new features by @zxj5470, and get some bug fixes.

• Fix implicit multiplication after ()
• Fix some deprecation (especially error reporter)
• Added 1.0 and 0.6 API list (so you have clear understanding of version-specific APIs)
• Julia 1.0 compatibility improvements
• Unicode input user experience improvement
• Fix error when git does not exist
