Circleguard

* add a popup explaining dragging when the user adds at least one loadable and check for the first time
* add message that displays when no cheat is found or displayed in a run
* warn users if they are using an api v2 key instead of v1
* fix errors not printing to the main textedit
* add tooltip to inactive run button telling users to input an api key
* add default map and user span options
* treat maximum threshold value as "infinity" (everything is displayed / treated as cheated)
* make api key wizard page the second page
* clarify that frametime is cv in results / template
* fix error in runs sometimes leaving progressbar at 100%
* fix excepthook not printing exception type

* add toolbar for frametime graph
* break the frametime graph along the x axis if there is a very high frametime (>50) (94)
* fix some undownloadable replays crashing a run. They are now skipped, and a warning is printed. (93)
* fix manual analysis erroring when no replays are provided
* don't limit Manual Analysis to only one `Loadable` (95)
* update message for multiple maps in analysis

* change the dropdown and "+" button for loadables and checks to just a dropdown, which adds the object on selection. This is a tradeoff between two clicks to add a new object, but only one click to add an additional object which you already selected (previous) and always needing a click and a drag to add an object, even if you just added another one of the same type.
* add frametime graph and replay data viewer. Look for the "more" dropdown on results in the results tab. These will only appear when your check has one replay.
* rename `Visualize` to `Manual Analysis`, as it now includes frametime/replay data as well as visualization

* fix using `NC` or `PF` in the `mods` field not working as expected (it was previously necessary to add its counterpart, ie `DT` or `SD`)
* fix replay stealing result label sometimes having mods for the two replays swapped
* standardize replay stealing messages
* fix a typo in timewarp template

* fix v2.6.0 checks not working

Because the v2.6.0 release got overwritten (accidentally), here's the changelog for it:

* add timewarp detection. This works by taking the average (median) of the time between frames of the replay, and alerting you if it's abnormally low.
* fix the beatmap test button in settings spanning the entire screen width

We are aware of the `Circleguard.lnk` file not working. Please use `Circleguard.exe` instead (located inside the nested circleguard folder) for now. We're looking into fixing it.

* code cleanup that may have broken a few things. If anything is off or wrong let us know!
* add Folder Chooser for local replays
* fix false positives in aim correct (see https://github.com/circleguard/circlecore/pull/144, which was the root cause and subsequent fix)
