DlangIDE v0.8.0 released

[Vadim Lopatin]

New DlangIDE version is released.

Prebuilt win32 binaries are available on 
https://github.com/buggins/dlangide/releases

Milestone 0.8 is reached.
List of 56 issues closed in this milestone: 
https://github.com/buggins/dlangide/milestone/2?closed=1

As well, many DlangUI changes were implemented for some of 
DlangIDE features.

Thank you for everyone who reported issues / sent PRs and feature 
requests.

Now I'm considering DlangIDE as mostly usable.
