This commit implements a simpler fix for the problem described in #1209.
The setting's signal is connected to a reset of `completionInProgress_`
so that the completion model is updated on the next word already.
This commit also removes the older approach tackling this issue.
This commit fixes a bug that would occur when changing the completion
mode from prefix-only to substring while mid-completion.
In that case, the suggestion list was not updated until the next
completion attempt.
This is fixed by forcing a suggestion list refresh whenever the
setting's checkbox is updated.
* 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.
