This adds the previous style changes in the license header (for
consistency) in the ignore-revs file

The license.txt file has been replaced with LICENSE for quite a while
now. INAL but it didn't seem accurate to say "hey, checkout license.txt
although there's no such file". Apart from this, there were
inconsistencies in the headers altogether...this change brings
consistency.

These modules were imported from the ERPNext codebase into Frappe.
License header was overlooked at that point. These were contributed
initially by Frappe Technologies Pvt Ltd under GPLv3 (ERPNext's license) and now
we, as Frappe Technologies Pvt Ltd converting them to MIT to comply with
Frappe's license.

feat: Query Builder autocomplete hack

coveralls badge -> codecov badge

fix: Enable Server Scripts by default

Why?
- Coveralls had login issues and we were not able to view files to find the actual uncovered lines
- Codecov has better reporting (status checks & commit diff coverage, ), UX (better folder/file navigation, faster page loads), and has more features.
- Codecov will not require additional step of
coverage wrap-up for parallel builds (it manages it internally somehow).

fix(frappe.utils.data): Deprecate `cast_fieldtype` to use `cast` for consistent return types

fix: Workspace 2.0 issues

fix(cleanup): cleanup email account, bug fix for web_template.js and more

This is sort of a breaking change? Because if an int/dict/list/tuple was
passed instead of a str, object doesnt have .startswith (AttributeError)
would be raised instead of just returning None.

* Return date and datetime objects for Date and Datetime field types
  respectively if Falsy output is set

get_timedelta returns None in case of invalid or imparsable inputs. This
behaviour is consistent wrt other utils. The util, to_timedelta tries to
convert to timedelta objects only if str object is passed. It returns
the same object if not string, which is absurd...given its called
`to_timedelta`.

fix(ci): Run all builds on github push events

* reference: revert Breaking Change -
  https://github.com/frappe/frappe/pull/13989#discussion_r695624003
* Show deprecation warning unless `show_warning` is unset

Issue: No PR number is detected on Push events and all builds are
skipped. We want the opposite to be true, so we're running all builds on
merges in hopes of testing better.

fix: Handle null values in auto email report rows for XLSX format

If ConnectionError or BusyLoadingError occurs, try every second for
up-to 10 times.

Why: `bench start` exits just as i run it at times. This happens when
the worker's processes each try to fetch a redis conn but redis isnt up
yet. The 3 workeer processes exit with 1 and our procman gives up too.
