Bumped version to 1.8.0

This stores project-specific settings, such as filesystem paths, for each
project, and restores those settings when the project is selected again.
Does not touch settings that haven't been set for the newly selected
project.

 # Blender Cloud changelog
 
-## Version 1.7.3 (in development)
+## Version 1.8 (in development)
+
+- Distinguish between 'please subscribe' (to get a new subscription) and 'please renew' (to renew an
+  existing subscription).
+- When re-opening the Texture Browser it now opens in the same folder as where it was when closed.
+- In the texture browser, draw the components of the texture (i.e. which map types are available),
+  such as 'bump, normal, specular'.
+- Use Interface Scale setting from user preferences to draw the Texture Browser text.
+- Store project-specific settings in the preferences, such as filesystem paths, for each project,
+  and restore those settings when the project is selected again. Does not touch settings that
+  haven't been set for the newly selected project. These settings are only saved when a setting
+  is updated, so to save your current settings need to update a single setting; this saves all
+  settings for the project.
+- Added button in the User Preferences to open a Cloud project in your webbrowser.
+
+
+## Version 1.7.5 (2017-10-06)
+
+- Sorting the project list alphabetically.
+- Renamed 'Job File Path' to 'Job Storage Path' so it's more explicit.
+- Allow overriding the render output path on a per-scene basis.
+
+
+## Version 1.7.4 (2017-09-05)
+
+- Fix [T52621](https://developer.blender.org/T52621): Fixed class name collision upon add-on
+  registration. This is checked since Blender 2.79.
+- Fix [T48852](https://developer.blender.org/T48852): Screenshot no longer shows "Communicating with
+  Blender Cloud".
+
+
+## Version 1.7.3 (2017-08-08)
 
 - Default to scene frame range when no frame range is given.
 - Refuse to render on Flamenco before blend file is saved at least once.
