[TYPO3-core] FYI: Added feature #17761: htmlArea RTE: Defer access to stylesheets

[Stanislas Rolland]

FYI: The attached SVN patch was committed.

Type:
Bugfix

Problem:
During its initialization, the RTE checks whether or not the stylesheets 
are accessible. If the stylesheets cannot be accessed, the RTE waits 
until they become available. If for some reason the stylesheets do not 
become accessible, the initialization process never ends.

Solution:
The attached patch defers the check on the stylesheets until after 
initialization has completed.
If the stylesheets do not become accessible, the blockstyle and 
textstyle dropdowns will remain empty. The contents of the RTE may not 
be styled as intended. A warning will be written to the javascript (or 
TYPO3) console.
If the stylesheets do become accessible, the initialization may be 
slightly shorter.
