Added extra check if editing and remove action from url
CSS fix for focus border on input of autocomplete
Yeah I know, groups didn't really make sense in a private messaging type app, the purpose is to be able to start a common individual dialogue with all course members or group members with receive capability hence new setting in course module usecoursegroups or restricting users to i.e students to opening dialogues with only people in groups they belong, also listing by role removed until fully developed. Autocomplete will load first 10 users without using alphabet.
Add usecoursegroups field, added new 2.6 decode temp info
Removed groupmode dropdown from conversation page
Fixed restore code to handle old backup files in 2.5
