* Make emote tab completion search for substrings
Previously, tab completion only searched for emotes that start
with the current prefix under the cursor. This commit makes tab
completion look for the current prefix as a substring in any position,
not just the start.
Examples:
* In forsen's channel, tabbing on "pls" will cycle through "DonaldPls", "forsenPls",
"GachiPls", "nyanPls" and "SourPls".
* As a forsen subscriber, tabbing on "sen1" will complete to "forsen1".
* As a pajlada subscriber, tabbing on "shrug" will cycle through
"pajaShrugL" and "pajaShrugR". (Unless you are in a channel with
more "shrug" emotes, of course.)
* Add a setting for prefix and substring completion
This commit adds a setting under the "Miscellaneous" section to allow
user to choose whether they want prefix-only or substring emote
completion.
The QCompleter filter mode and `addString` function are now chosen
according to the user's setting.
* Improve description of emote completion setting
Also reintroduce a blank line that went missing.
"Stack" is the default behaviour, it will search 20 messages up and 5
seconds back in time to stack the timeout.
"Stack sparingly" will try to do the same, but only if the user has not
typed a message inbetween the this and the last timeout.
Fixes#1157
Inline whispers will be displayed with highlighted background color.
New Flag needed to differentiate between normal whisper (highlighted) and whisper with mention.
changed setting from String to int.
changed EnumCase
I used createComboBox only has an implementation that handles stringsettings. I implemented my own combobox to handle the ToastsSettings now. Not sure if this is the best way. Won't come up with something smarter for now.
Implemented #710
Added options for opening streams from clicking the toas notficiation: (according to options in splits)
- open in browser
- open player in browser
- open in streamlink (needs to be tested, but should in theory work, since I only use the already existing function)
- don't open the stream (in case someone wants to prevent opening streams "by accident")
