tcWebHooksPlugin 1.2.0-alpha.6

Bugfix release - Sixth alpha release of 1.2.0 version

Testing a webhook from Edit dialog does not always use correct template. Issue #157

When testing an existing webhook by using the Preview and Test tab in the WebHook Edit dialog box, the template used for preview and test was the one configured for the webhook, regardless of which template was chosen in the edit dialog. This is now resolved and any template can be chosen for preview/test even without saving the webhook.

Viewing WebHooks in Project Configuration does not display webhooks if no template associated.

Since 1.2.0-alpha.5, support was added for templates associated with projects (rather than only being able to be editing by a system administrator).
However, if no templates were associated with a given project, the webhooks and templates tab would not load in that projects Configuration settings. It would fail trying to build a list of non-existent associated templates.

Add suppport for TeamCity 9.x #156

We still have some users on TeamCity 9, and this fixes a bug in the REST API which was preventing TC9 users from editing templates. This incompatibility was introduced in 1.2.0-alpha.3
