Fixes for the 1.3.0 release

[George-cl]

Summary

This includes and builds on the current develop branch (15bd0d7).

Outline of work:

Description	Fixes	Commit
Improvements to error handling.	N/A	N/A
Disables the Connect toggle if the current site is not listed in the manifest (and is therefore not integrated). Any non-integrated sites saved from previous versions will be removed for consistency.	#103	1260a59
Increases the idle timeout from 30 to 60 seconds. The value is now set in the app state which will make it easier to configure by users via a Settings section in future.	#111	b76c2d2
Viewing account details no longer makes the account Active	#119	a2f56fe
Allows users to upload secret key files in either .cer or .pem format	#91	304d301
Restricts names when renaming accounts - this is to ensure names created with the constraints can't then be edited to break the rules.	#114	8aa90bc
Payment is now displayed properly in UI. Only supports StandardPayment	#106	84bfa3e
I have confirmed that this is resolved with proper use of the Event Bus - tested in Signer Demo	#115	N/A
Initial implementation of parsing for arbitrary deploy arguments. The support is limited but should allow clients to send a broader range of deploys and have the data displayed in the Signer. More complex args such as Tuples and Lists don't display well - this will be improved in future.	#95 (Partial)	53f8696
Removes secret key field from Create Account screen. This is to prevent users manually copying the raw base64 key as a backup. Importing requires a .PEM formatted key file and we actively discourage storing keys in raw form for security reasons.	N/A	e298a3f
Fixes an issue where some screens would go blank when locking instead of returning to the unlock screen. (This is still a WIP issue for Create/Import screen)	#112 (Partial)	d047098
Persists Active Account between sessions. It will resolve errors experienced by some users when they had to unlock during the signing process.	#120	4f9dbd6

Tested this and payment info does show in the transaction sign page now - in future we may need to revisit the Labels though
